[gimp/multi-stroke: 30/30] app: memory leak fixes.

[Jehan Pagès <jehanp src gnome org>]

commit 36e4397daff2b509417f713ab76908ecaed718ba
Author: Jehan <jehan girinstud io>

    app: memory leak fixes.
    
    Thanks Massimo:
    "The GList*  returned by 'gimp_image_symmetry_list' is not freed in few places
    and the char* returned by 'gimp_symmetry_parasite_name' is passed directly to
    functions that do not free it and so it is leaked."
