[LyX/2.4.x] Remove setBuffer call in Cursor::push.

[Jean-Marc Lasgouttes]

commit 46d1d6e0d384bea969a55426bef22e03bc231bf8

    Remove setBuffer call in Cursor::push.
    
    This is potentially slow. It also should be unnecessary after
    some of JMarc's recent commits. See bug #13050.
    
    (cherry picked from commit 66cfc6af3c764b6923aae6c134c43c2155317c6a)
