Drop support for registration resurrection (Unregistering then quickly re-registering would resurrect the original registration instead of creating a new one). This behavior is no longer in the specification (No more "isUninstalling" flag on the registration, and the registration is removed from the "scope to registration map" right away upon unregistering). This resurrection behavior was causing a lot of flakiness in the tests so it is likely we will be able to unskip some tests. This is also what was causing the flakiness that caused Bug 201169 to be rolled out.
