Fix freeze when triggering window switcher

[RonSkons]

Ran into a similar problem to the freezing described in #215 when attempting to use the X Window Switcher plugin. When typing after triggering the window switcher, Albert becomes unresponsive and ultimately has to be killed.

I've applied the fix for the freezing bitwarden plugin to the window switcher, which resolved the instability. Instead of calling query.add in a loop, this version accumulates results in a list and only calls add one time.

I think this pr is obsolete with the recent commit fa95ed9

can you please test it (install albert-git)?

this plugin has no maintainer at the moment. do you mind to step in as maintainer?

Hi Manuel, this looks to be fixed on albert-git.

I’m open to stepping in as maintainer, with the caveat that my availability is somewhat limited.
Based on the current level of activity, I don’t think that should be a bottleneck

thank you.

with the caveat that my availability is somewhat limited.

thats perfectly fine. we all have our real lifes. if the plugin is working there is actually not much to do for a maintainer. Not even API changes because i usually script them if possible.
