Fixing “Transition Delay - App to Recents” test: the Launcher part

The fix is quite hacky and should be re-done soon. I’m not leaving TODOs
in the code, but I’m tracking the cleanup elsewhere.

We also need a fix in the server to make the test work, but that will be
another CL.

Bug: 72967764
Test: atest google/perf/app-transition/app-transition-to-recents
