Make wire compatible with html formatter

[aurelien-reeves]

Description

Fixes #56

It seems that the wire protocol is not compatible with the html formatter.

Note to other contributors

Tests seems to be failing due to the usage of hooks in the wire plugin and how they are managed by new formatters using messages.

I may have found a fix: emitting the hook_test_step_created when adding the hooks filter.

Bonus: when working on that, I was able to remove the only use to cucumber::messages, thus the dependency to messages itself.

This is still a draft because it may be refactored, and also I would prefer having your opinions @luke-hill @mattwynne

@canmor would you have the possibility to take a look? That should actually fix your issue reported in #56

Well, actually it was not really finished, sorry 😅
