Print full startup/initialization error (#15569)
I found the error in the **Before** really vague and obtuse and didn't realize port `5432` corresponded to the Postgres port until searching the codebase. It says to check the logs but that wasn't my first instinct. It's just more obvious if we just print the full thing which gives context of the error type and the traceback to the relevant area of code.

#### Before

```
$ poetry run python -m synapse.app.homeserver -c homeserver.yaml
**********************************************************************************
 Error during initialisation:
    connection to server at "localhost" (::1), port 5432 failed: Connection refused
 	Is the server running on that host and accepting TCP/IP connections?
 connection to server at "localhost" (127.0.0.1), port 5432 failed: Connection refused
 	Is the server running on that host and accepting TCP/IP connections?
 
 There may be more information in the logs.
**********************************************************************************
```

#### After

```sh
$ poetry run python -m synapse.app.homeserver -c homeserver.yaml
**********************************************************************************
