Cleanup pip tests

Removing all tasks, going home, and setting initial and final orientation are done by the flicker infra automatically and don't need to be re-executed by the test

Remove these commands to improve test speed

Test: atest WMShellFlickerTests
Bug: 264637221
Change-Id: Ie3b31dfe0340126102d6178de2d4a58033adc955
