Ignore broken tests, fix flaky tests.

Filed follow-up bug to track re-enabling broken tests.  Flaky tests
were result of singleton race condition during start-up, so always
create CalendarSanityChecker as strong part of CalendarProvider2.

Bug: 139358215
Test: atest --test-mapping packages/providers/CalendarProvider
