Fixes around extract mode

Stop selection mode after Edit/Copy while in extracted mode.

The selection mode was started by a long press in the ExtractedEditText.
Selection Copy in the menu simply sends the id to the context menu.
SelectionMode is not stopped in the underlying text since it was not
started there. Stop it directly in the ExtractedEditText.

Cut and paste do stop the mode because the text is modified.
