fix(style): Format and lint test helpers

This commit fixes two issues:
1. Fix an issue where [PubSubManager.publish] would always, if given
   publish options with maxItems set to 'max', use 'max' in the
   max_items publish options, even if the server indicates it does not
   support that.
2. Fix an issue with the StanzaExpectation, where it would let every
   stanza pass.
