Subject: Fix for misaligned video view surface

* Stash the true height of mPrimaryCallCardContainer in a view tag
so that its height is not misreported during the outgoing call animation

* Move the onGlobalLayoutListener so that the callbacks occur after
the surfaces have been inflated, to ensure the views are non-null.
