Fix problem where launcher doesn't draw after rotation w/ translucent activity above it

-> Removed some code which caused this. The code was intended to fix a certain issue:
"Fixing issue where we were reverting to the first page of the workspace after
launching an application from all apps, rotating, and returning home"
-> That bug doesn't seem to occur anymore, even with the revert
-> See https://googleplex-android-review.googlesource.com/#/c/209561/1
