v2.0.4

v2 Breaking Changes

• If a phx_reply is returned from the server with an error status, this will now result in any waiting promises to reject with an error, rather than resolving.
• Furthermore, it can now be assumed that any reply sent to a promise resolver will have an 'ok' status, so any error handling code will need to be moved to a .catch() call on the promise.

Bug Fixes

• Various edge cases have been fixed which resulted in a waiting reply promise to hanging forever and never resolve/reject.
