Search bar in settings shouldn't end in back stack

[FinecoFinit]

After entering the search bar it needs to double click on back button to 1.(first click) close search bar 2.(second click) back to chat list. Also after entering search bar can't click on right up "hamburger" menu and can't exit search bar clicking on empty objects

Expected:

1. one click to return to chat list
2. disabling search bar by clicking on empty object
