Keybinding collision between 'Toggle Plugins View' and 'Select All Occurrences'

[RomanNikitenko]

Description

It's impossible to open Plugins view using keybindings when an editor is open.
I think the cause of the problem is keybinding collision between 'Toggle Plugins View' and 'Select All Occurrences'

Reproduction Steps

1. Try to use ctrl+shift+l to open Plugins view when you don't have open editors: it works.
2. Open an editor and try to open Plugins view using the corresponding keybinding.
   You can see that Select All Occurrences is executed.

OS and Theia version:
Fedora 31
Theia version: a187f01

Should we change keybinding for plugins?

[RomanNikitenko]

Now I can see another behavior: it always opens Plugins view when I use ctrl+shift+l keybinding.
So, now user can not trigger Select All Occurrences action when an editor is focused - Plugins view is open instead.

We can remove the keybinding for Plugins view. It is not used widely in production.
