Fix failing WebViewUpdateServiceTest.

WebViewUpdateServiceTest#testPreparationRunsIffNewPackage was failing
since the fix for b/140129991 was implemented, as we no longer consider
the update time of the package and early-out of triggering a preparation
run, to avoid issues with static shared library dependencies.

Remove the logic in the test that tries to prove we don't run additional
preparation passes when trivial package replacements occur, as we no
longer consider any package replacement to be trivial.
