Fix: avoid movement blocking to affect when closing emoji search

[davidejensen]

What does this PR change?

Fix #2527 (maybe also fixed #2477 )
Removes the input blocker management from the emoji panel as it's handled by the chat controller already

...

How to test the changes?

1. Launch the explorer
2. Search for an emoji in the chat.
3. Exit the emoji search using 'Esc', then the 'X' button, or by clicking outside the chat.
4. Try to move the avatar or use hotkeys like U, B, N, M, I.
