Multiples fixes for BBB 2.5

NEW-20 Protected recordings not working

There seems to be a bad regression with protected recordings after the last updates.
It seems that when playing a recording, even though it is protected, the requests are making use of the cached (or stored somewhere) URL. This should not be the case for protected recordings as the URL it is unique per getRecordings request. An alternative solution is to perform a getRecording when proceding with the playback, right before the user is redirected to the recording. This getRecordings request should not affect the cache in any way since the URL is useless for users other than the one who clicked the recording.
