Fix symbols duplication on keyboard paste hotkeys

[Andrei Salavei (ASalavei)]

Remove keyboard events handling from the text input view.
Skip edit menu events if there is an active key press detected.
Add logic that simulates key up events for started events with detached views - these events are not propagated by iOS.
Add ability to test key presses on simulator environment.
Add tests for key presses and text edit operations with hotkeys.
