[Sébastien Wilmet <swilmet src gnome org>]

    Fix tests when gtksourceview is not installed
    
    When running test-search-context when gtksourceview is not installed,
    there was this error:
    GtkSourceView-WARNING **: search-match style not available.
    
    The fix is the same as in test-languagemanager.c (but for the style
    scheme manager).
