feat/bug: filtering list of media players

[cristianoliveira]

Hello there! Thanks for this plugin.

I'm not sure if this is a bug or by design, I don't know how to classify, but what I noticed is once the list of players are presented if I continue typing it doesn't filter the items in the list.

Reproducing

• Have more than one player running like Brave - Youtube and Spotify
• Start typing in the ulauncher input
• See results

input: md 
result:
- brave: foobar
- spotify: bar

Current:

input: md spot
result:
- brave: foobar
- spotify: bar

Expected:

input: md spot
result:
- spotify: bar

Does that make sense? I can open a PR with a implementation for this, let me know
