Don't append suggested extension if filename includes extension

Commit 6b19a24b581c9c changed the way that the file name is composed
for a video recording, so that a suggested extension for the given
media format is appended to the file name.  That introduced a bug
in the case where the correct extension was already part of the
output location (filename) set for the sink, by causing a second
(and possibly incorrect) extension to be appended to the filename.

This commit ensures that if the filename already has a suffix, no
suggested extension is appended.
