[Bug] Labels with "_" are not valid arguments

[StummeJ]

This is a pretty cool slack plugin. I've however noticed when trying to filter the subscription by a label with an underscore in it, I get an error +label:something_with_underscores is not a valid argument. This happens when it's quoted (double or single) or just raw.

Cheers

+1 Still valid as of 10 December 2021.

Very frustrating, the error message is unclear as well. According to #1076 the fix should be a simple addition to a config file
