           Summary: ServiceWorkerRegistration objects may get recycled for

ServiceWorkerRegistration objects may get recycled for different SWServerRegistration objects, leading to flakiness in the tests. Right now, we use ServiceWorkerRegistrationKey as key in the m_registration map on WebProcess side. The lifetime of the ServiceWorkerRegistration objects is tied to the lifetime of their JS wrapper. When the test does a registration for a given scope, then unregisters, then registers again for the same scope, we end up creating a new SWServerRegistration object on server side, but possibly reuse the same ServiceWorkerRegistration object on WebProcess side, if the wrapper has not been garbage collected. This is because the registrations have the same ServiceWorkerRegistrationKey.
