Summary

A channel capability is created in ChanOpenInit. A channel capability is also created in ChanOpenTry. If a channel attempts to be created by calling ChanOpenInit but runs into crossing hello's and needs to call ChanOpenTry an error is returned stating the channel capability already exists.

A channel capability should only be created if the previous channel state does not exist.
