Fix specs which are incompatible with fast_spec_helper

This commit switches from `require 'fast_spec_helper'` back to `require
'spec_helper'` for specs which require application dependencies (e.g.
database baked feature flags, Rails).

It also adds some missing `require`s to "fast" specs so they don't fail
when run individually.
