package still exists after calling `pulsar-admin packages delete`

**Describe the bug**
After using `admin packages` delete a package, I can still list the deleted package:

```
➜ apache-pulsar-2.9.1 ./bin/pulsar-admin packages delete function://public/default/void@v0.1
"The package 'function://public/default/void@v0.1' deleted successfully"
➜ apache-pulsar-2.9.1 ./bin/pulsar-admin packages list --type function public/default
"void"
➜ apache-pulsar-2.9.1 ./bin/pulsar-admin packages list --type function public/default
"void"
➜ apache-pulsar-2.9.1 ./bin/pulsar-admin packages list --type function public/default
"void"
```

And the result of list version is:
```
➜ apache-pulsar-2.9.1 ./bin/pulsar-admin packages list-versions function://public/default/void
➜ apache-pulsar-2.9.1
```

**To Reproduce**
Steps to reproduce the behavior:
1. Go to '...'
2. Click on '....'
3. Scroll down to '....'
4. See error

**Expected behavior**
After a package deletion, the `list` should not return the package name
