[FIX] web_editor: cursor one step late in collaboration

Reproduction:
1. Install note
2. Open an existing note and open it again in another tab
3. When you click in one tab, the cursor position in the other one is
always one step behind

Fix: separate the logic between collaboration and appliedCustomSelection
and revert the calling of getCurrentCollaborativeSelection to the place
after _computeHistorySelection
