Alex Tanskanen 15c74e7dc9 Fix missing caps lock events on iOS
Caps Lock on iOS only trigged key release or key press events.
When it's clicked it would only send keydown, and next time
it would only send keyup and so on. It should send both a key press
and a key release.

Also added the unit tests for macOS since those were missing.
