Duplicate filenames cause recording failure

[smarquard]

We had a CA with an incorrectly configured conf.ini with multiple references to

file = presenter.mkv

once in the correct track, and twice in a presentation track, after the declaration of another file = ....

This caused complete recording failure in a non-obvious way; it seemed to record, then hung when trying to copy the recording from rectemp to a repo location.
