[meld] Clear inline highlighting cache on refresh/reload

    Clear inline highlighting cache on refresh/reload
    
    Without this change, inline highlighting marks disappeared on reload
    and did not reappear, and refresh/reload reused cached inline
    highlighting information. Here, we clear the cache to force
    recalculation and redrawing of highlights.
