    gtktext: Also reset IM context after IM surrounding text deletion
    
    When the IM commands the GtkText to delete text, the cursor position
    would change, and so would the surrounding text. Reset the IM context
    so that these updates are properly picked up by the IM.
    
    Fixes backspace key behavior in the GNOME Shell OSK, since that relies
    on the surrounding text being properly updated for the next iteration.
