we find a better way to reimpliment it in a  more sane way

Found 3 spec files that were never getting run because they didn't have the _spec at the end of the filename. This commit renames them, so that they are now included in rake spec. Unsurprisingly, they all fail. Since they represent actual changing code that isn't tested, I'm checking them in anyway. Thx Pistos for pointer to the first file, which prompted me to look for others.

fix specs; move presence_of_content validation check into a before_destory to play nicely with federation

The old implementation which uses Post.where causes

  undefined method `abstract_class?' for Object:Class

in spec/controllers/posts_controller_spec.rb.  Not sure whether that's a problem
with Rails, or rspec, or what.

Original (root) posts should simply have "Reshare" as the English link text (not "Reshare original").

even more spec fixing, postgres throws statement invalids for duplicate keys, luckily record not unique is a subsubclass of it so we can just catch the higher error

fix diaspora connect for the new oauth stuff WIP. There's one bug where the oauth_identifier changes but the client doesn't get informed or doesn't save it. I hope it's the last bug. Btw. this is all ugly
