TableBuilder spec: Get past Pundit errors

Add a bunch of mocks etc. to get past errors related to using Pundit
inside the helper. These errors included:

* No method `policy` (included `Pundit` in `TableBuilderHelper`)
* No method `authenticate` (mocked a `current_user` method on the
  helper)
* Need to return a `user_context` from `current_user` to make policy's
  `#new` happy (no method `user` on `User`)

At first tried to use the `create_user_context` method from
spec/support/pundit, but it wasn't in scope so I just did it directly to
get it working.

Don't like all the mocks at all. A lot of pre-work to do just to get the
helper to execute without exceptions.
