Recover from being unable to end the video recording stream

[brian-mann]

It appears that there are conditions to which a video recording stream cannot be finished as per these Travis CI logs: https://travis-ci.org/gpincheiraa/bln-frontend-project1/builds/399205721

I'm unsure what the underlying issue is, but regardless we need to simply add a timeout around this promise not resolving and continue on. It'll take a bit more digging to understand the underlying issue and whether or not the video is useful or corrupted at that point.
