Fix all existing context matching to be consistent across the repo

[fidgetingbits]

I got confused while doing a review yesterday on #1401 because I happened to be looking at https://github.com/talonhub/community/blob/main/core/application_matches.py around the same time and we are constantly using and where I guess we don't need to. I think almost (not all) of those are redundant?

Also just quickly poking around elsewhere, eg https://github.com/talonhub/community/blob/main/apps/outlook/outlook_win.talon, we are using and where it isn't needed.

Probably makes sense to fix all these to not have superfluous logic, where https://talon.wiki/customization/talon-files/ is probably the best reference of the AND and OR behavior.

If I'm derping here still, I'm happy to be corrected :D
