FileChooserWidget: Fix leaks in .get_subtitle()
Now that subtitle's default value "Searching" for OPERATION_MODE_SEARCH is duplicated as it should be, we cannot reassign other strings to it anymore, as that resulted in the original dupe of "Searching" leaking. Fix this by only assigning the dup'd "Searching" after trying to get more specific values, not before. We therefore need to set it to NULL during its declaration, and that means we needn't in the final else.
