Fix some shell transitions bugs breaking splashscreen cts

Browse Source 
Splashscreen CTS uses its own HOME activity that gets placed
on top of the normal launcher. Prevent the launcher's remote
transition from responding in that case by adding a component
filter to the TransitionFilter class.

Bug: 194112093
Test: atest SplashscreenTests
