[kara]

Some lifecycle hook tests are failing on Travis because of the new enterView call in ViewContainerRef.

@kara not sure which tests exactly are failing for you in the unpredictable way but I can see some random pass / fail for a few lifecycle-hooks related tests locally. This happens after pulling the latest master but I can see this under Chrome, so probably not FFox specific (assuming that we are actually hitting the same problem...)

@pkozlowski-opensource I actually can't repro the failures at all locally, but they are failing on Firefox on Travis CI here (but not Chrome):

I'm pretty sure it has to do with entering the view in this way, which was only a hack until we could re-write the view container implementation anyway. Reverting the change fixes the tests.
