[wsv2] Rely on the metadata to provide the full url (#221)

We have so many places where the magic string `/wsv2/${token}` is
constructed and it's hard to keep track of all of them.

This change now makes the crosis library rely on the explicitly provided
URL instead of re-inventing the wheel.

…to unilaterally abort. (#193)

* Restore the option to return aborted; add invariant check.

* v13.1.0. (#194)

[13.0.0] (#190)

* Bump incompatible protocol.

* Add required userId.

* Prevent openChannel() from returning an unusable channel.

* Split test into the two conditions, handle them both with an await.

This is a change of behavior, but its the change of behavior we intended back in 10.0.0. You can't get a channel callback without a valid channel anymore, so we have to actually wait for it to open to see `firstChannel`.

* to 13.0.0
