Fix unlocking multiple databases with pw-stdin when input is a pipe

Browse Source 
This works:

```
$ keepassxc test1.kdbx test2.kdbx --pw-stdin
Database password: <manual input 1234>
Database password: <manual input 4321>
```

But this doesn't (only `test1.kdbx` is unlocked):

```
$ printf '%s\n' 1234 4321 | keepassxc test1.kdbx test2.kdbx --pw-stdin
Database password:
Database password:
```

The problem is that `Utils::setDefaultTextStreams()` is called multiple times
when unlocking multiple databases with `--pw-stdin`, which appears to break the
pipe. Simply call it once to avoid the problem.

Fixes: #5012 (as far as I can tell by simulating the script in Linux)
