[Bug] Synced data stored as unsequenced

### Search before asking

- [X] I searched in the [issues](https://github.com/apache/iotdb/issues) and found nothing similar.

### Version

Both machines running Ubuntu 20.04 and docker image of IoTDB version 1.2.2

### Describe the bug and provide the minimal reproduce step

1. Start two nodes in standalone configuration
2. Set pipe to cloud node
3. Perform insertions at the edge node

### What did you expect to see?

All data inserted to be stored in the same manner on both nodes.

### What did you see instead?

Although on the edge node data is stored in sequence TsFiles, the cloud node treats synced data as delayed and the data is stored in unsequence TsFiles.

On the cloud node running `du -h .` on the data folder shows most data usage in unsequence files
```
4.0K ./datanode/data/sequence
6.9G ./datanode/data/unsequence/root.gps/2/2808
6.9G ./datanode/data/unsequence/root.gps/2
6.9G ./datanode/data/unsequence/root.gps/1/2808
6.9G ./datanode/data/unsequence/root.gps/1
6.7G ./datanode/data/unsequence/root.gps/3/2808
6.7G ./datanode/data/unsequence/root.gps/3
6.4G ./datanode/data/unsequence/root.gps/4/2808
6.4G ./datanode/data/unsequence/root.gps/4
4.7G ./datanode/data/unsequence/root.gps/5/2808
4.7G ./datanode/data/unsequence/root.gps/5
32G ./datanode/data/unsequence/root.gps
32G ./datanode/data/unsequence
32G ./datanode/data
```

While on the edge nodes running `du -h .` on the data folder shows most data usage in sequence files
```
8.6G ./datanode/data/sequence/root.gps/2/2808
8.6G ./datanode/data/sequence/root.gps/2
6.9G ./datanode/data/sequence/root.gps/4/2808
6.9G ./datanode/data/sequence/root.gps/4
7.6G ./datanode/data/sequence/root.gps/1/2808
7.6G ./datanode/data/sequence/root.gps/1
7.1G ./datanode/data/sequence/root.gps/3/2808
7.1G ./datanode/data/sequence/root.gps/3
30G ./datanode/data/sequence/root.gps
30G ./datanode/data/sequence
26M ./datanode/data/unsequence/root.gps/2/2808
26M ./datanode/data/unsequence/root.gps/2
17M ./datanode/data/unsequence/root.gps/4/2808
17M ./datanode/data/unsequence/root.gps/4
26M ./datanode/data/unsequence/root.gps/1/2808
26M ./datanode/data/unsequence/root.gps/1
26M ./datanode/data/unsequence/root.gps/3/2808
26M ./datanode/data/unsequence/root.gps/3
94M ./datanode/data/unsequence/root.gps
94M ./datanode/data/unsequence
34G ./datanode/data
34G ./datanode
```

Tests performing query operations seem to indicate that this negatively impacts query performance as unsequence files negatively impact query performance. These tests were run using IoTDB version 1.1.1, but since data is still stored as unsequenced in 1.2.2, this behaviour should still be present.

### Anything else?

Edge node is running in a Docker container limited to 4 CPU cores, 4GB of RAM, 44MB/s disk reads, 40MB/s disk writes, 2700 read IOps, 1200 write IOps
Cloud node is running in a Docker container with no limitations. Host machine has a 6 core CPU and 16GB of RAM

### Are you willing to submit a PR?

- [ ] I'm willing to submit a PR!

Start by reproducing the two-node standalone setup with the IoTDB 1.2.2 Docker image, configuring a pipe from the edge node and inspecting the cloud node's datanode/data/sequence and datanode/data/unsequence folders. Compare the stored files and query behavior after edge insertions; done means synced data is stored as sequence files on the cloud node without the reported query-performance impact.
