Handle invalid window id more robust

Describe the bug
When using t-rec with an invalid window id like WINDOWID=2417444 t-rec then no error is shown until you end the recording with CTRL+D. Only then an error like this is shown:

Error: Cannot stop the recording thread

Caused by:
    sending on a closed channel

Expected behavior
an error with more details should be shown immediately on start.
