VID-1769 debugging race conditions with videos module load

Don't merge just yet, need to verify my implementation
@nmonterroso does this seem okay to you?  I saw in the Kibana 101 slides that for JS we should check in with you before using it. 

In the past I've used GA for this sort of thing (i.e. temporary debugging) and I can continue to use that if this will have performance implications. The videos module gets loaded on the majority of page views, so if this slows us down that's not a good thing.
