Ensure that files are handled safely in recording scripts

This commit fixes an issue with reading and writing files.
File.open is used which means that a file will remain open
unless explicilty closed or the program exit. This doesn't work
for an NFS mount as the scripts try to "rm -rf" when the file
is still open. This commit fixes that by replacing all .opens
with .reads

Clear video streams collection

After the code to mirror the video-preview component was added
I noticed that I improperly used the userId property of an undefined
argument as the video-preview does not have a user as a prop. This
commit decouples the logic to verify if the webcam should be mirrored
and whether the webcam belongs to that user. In the latter, we verify
if the user parameter exists and use it in a conditional, otherwise
we simply return true (applies with the video preview component),
where there is only one video stream.

Update minimist to latest version.
