ADD: system tests for wiki edits

[Uzay-G]

For part of #5316

I added a test that verifies that users can edit wikis and preview their contents. What do you think @VladimirMikulic?

On my server, the test fails. Let's wait for Travis though.

This is weird. It is working for me...

There were differences between my fork and this repo. I need to find a way to select the edit button for the wiki. I will work on this tomorrow!

[VladimirMikulic]

@Uzay-G this will make your test work:

find('.like-buttons a.btn-circle:first-of-type .fa-pencil').click()

100% precision :)
