DO NOT MERGE: Remove testAddTwoToastsViaAddingWindowApisWhenUidFocusedQuickly.

The described behavior doesn't match on what nougat-mr1-dev framework does,

The other test case, the WhenUid"Un"Focused, can be still kept to ensure
unwanted apps not to occupy the foreground by multiple toasts.

Bug: 37088966
Test: None (this CL is just removing a test.)
