Fix race condition when an observer calls claim_with then accept the contextHEADmaster

tp_channel_dispatch_operation_claim_with_async() were preparing itself as first
step, which means the dbus call is not made directly, and the tp_observer_context_accept()
dbus message could get to MC first, making MC dispatch the channel to any capable handler.

There is no reason to prepare self in _async calls, caller is responsible for that.

Fixes fd.o#42503
