theme: Check the return value of _elm_theme_group_file_find() and do not

pass NULL to eina_file_filename_get().

eina_file_filename_get() spits unnecessary eina error when the parameter
is null. In this case, we need to check the return of
_elm_theme_group_file_find() and do not call eina_file_filename_get()
	when the return is null. One should check the return of
	elm_theme_group_path_find().
Thank zmike for pointing this out.
