taglist, plugins: fix compiler warnings with GLib >= 2.76

Browse source 
Fix compiler warnings about not using the return value when
freeing the GString segment with g_string_free(.., FALSE):

    ignoring return value of ‘g_string_free_and_steal’ declared with attribute ‘warn_unused_result’

which we get with newer GLib versions. These were all harmless.
