Fix arguments for hevercardable helper

We should pass person object to the hovecrardable helper. In the
current case `this` is the status message, not the status
author. So, let's pass `author` instead of `this`.
Tests for hovercard in reshares

Coverage with tests is necessary for every feature
Use capybara hover method in the hovercard steps

Let's use methods provided by capybara whenever possible.
Make step name more logical
Make feature consistent with other features.

Actually, I just trying to make this feature pass.
Check user name presence instead

It seems that loading of stream is not completed before trying to activate hovercard.
I do not want to add explicit pause to the scenarion. Let's check link presence before activating hovercard.

Merge pull request #4842 from seanbrant/patch-1

Fixes typos
Introduce message renderer

This new class replaces all existing server side message
rendering helpers and is the new global entry point for such
needs. All models with relevant fields now expose an instance
of MessageRenderer for those. MessageRenderer acts as
gateway between the existing processing solutions for markdown,
mentions and tags and provides a very flexible interface for
all output needs. This makes the API to obtain a message
in a certain format clear. As a result of centralizing the
processing a lot of duplication is eliminated. Centralizing
the message processing also makes it clear where to change
its behaviour, add new representations and what options
are already available.
