This reverts commit 19ebd61442fd3bf6a69af2156c8b118fc8578ec2.

Additionally, the following _flutter.runInView deadlock is fixed.

Previously, a deadlock would occur when service protocol
_flutter.runInView is used to restart the engine wihtout tearing down
the shell: the shared mutex of the service protocol will be locked
during the restart as it's in the middle of handling a service protocol
message; if ServiceProtocol::AddHandler is also called during the
restart, the deadlock happens as AddHandler also requires such lock.

test/integration.shard/background_isolate_test.dart would fail
without this fix.
