Fix flaky two panel TAPL tests v2

Cuttlefish emulators are getting slower and slower and some
of the two panel related TAPL tests were failing
due to multiple page changes instead of single ones, so
we need to increase the page change hover time in the tests.

Test: atest -c NexusLauncherTests:com.android.launcher3.ui.workspace.TwoPanelWorkspaceTest
