analyzepsbt causes elementsd to crash with assertion when given a funded psbt

I created a funded psbt with walletcreatefundedpsbt like so:

```
elements-cli walletcreatefundedpsbt [] "[{\"AzpxinPHtswVettidEhUXDeWjo3msP1A9Je5LFhQaQn5Ppf8owJCpDwjiQ6EF9YqXBAMU7BA4MKaJbba\": 0.005}]"
```

Got back this base64:

Passing the base 64 to analyzepsbt causes my daemon to crash:

Make sure the daemon server is running and that you are connecting to the correct RPC port.
```

With this in the debug.log:

```
elementsd: ./primitives/confidential.h:140: CAmount CConfidentialValue::GetAmount() const: Assertion `IsExplicit()' failed.
```

Tái hiện crash bằng PSBT đã được cấp vốn được cung cấp, sử dụng lệnh analyzepsbt, sau đó kiểm tra primitives/confidential.h xung quanh CConfidentialValue::GetAmount() tại dòng 140 và theo dõi cách analyzepsbt xử lý dữ liệu giao dịch. Công việc được xem là hoàn tất khi analyzepsbt không còn kết thúc elementsd với assertion IsExplicit() khi nhận PSBT này.
