Fixed close tab NPE
Bug: 3293676
This was caused by two problems. The first was the code to determine
the child draw order could break. This cleans up the logic to hopefully
be clearer and fixes the problem, it is more robust. The root cause
though was that you could have two tabs pending being closed due to
a broken animation. This simply removes the animations completely for
now, how tab open/close should be animated can be addressed in another CL
