Typo prevented calling len on maps.

Had a bug where could not run one message sequence after another
message sequence in the same event.  This was because after issuing a
message sequence, I did not reset each context's to_reply_with_uuid
field.  The to_reply_with_uuid field tells the other side whether or
not this is the first message in a sequence (if == None).
Minor typo when emitting backout exception.

Previous code had an issue where was beginning a message sequence
within another message sequence (via get_other_side_endpoint).  Fixed
by passing endpoint directly.  Also added a test case to ensure that
two nodes can connect to each other.
