Require the cypress on rails dependencies very early in the engine

Since the rails app Gemfile has these configured with require false, we need to
do the require early in the engine.  config.before_initialize is NOT early
enough.  config.before_configuration happens before config/application is
required.

Note, before_initialize didn't work as evidenced by the middlware not
processing the requests for /__e2e__/command.
