[Video Recorder] Fail to record multiple video streams

[joaoantoniocardoso]

Two detected issues when trying to record multiple video streams:

1. If a second Video Recorder MiniWidget is added while the first is in recording mode, it interrupts the recording and it seems that the first widget goes to a weird state.

2. An error "Cannot load media stream" appears, shown in the video below: (fixed by Video store rules all #654 )

cannot_load_media_stream.mp4

Update after #654:

The error "2" is fixed, but the error "1" remains -- the recordings stop if you add another recording widget:

recordings_stop_if_another_record_widget_is_added.mp4

recordings_stop_if_another_record_widget_is_added.mp4

I expect that to be fixed on #655.
