A few places all use the domain.intern() as the key for a synchronized block.

This can lead to clashes when multiple semantics conflict, and this can in turn
lead to a deadlock, as witnessed in OF-984.

This changes two cases to use a prefixed string to namespace the locking.

OF-983 appears to be caused by a complex bouncing process run while the
authentication check lock is held. This patch moves the actual bounce to
outside the synchronized block, so the code no longer deadlocks.

Untested, but based on the stack traces in OF-983 reports.

Revert "OF-115 Remove race during outgoing session creation"

Ignore test that makes Travis fail.

This reverts commit d0667e21.

While I think the general code is right, it's clearly got serious shortcomings
so I think it's best to back this out for now.
