The "Video consumption Examples" view in SupportLeanBackShowcase was failing on
the master build (fugu-userdebug N AAC30 2573265 devkeys),
since onCreate gets called in the reverse order of fragments' appearence in the
code when using a single transaction.
Fixed that by using separate transactions per fragment addition, and now the
example video view works on the master build as well as the LMP-MR1 build.
