Move "I should see Crowd login form" feature to a view specrs-crowd-form-view-spec

We were doing all kinds of code gymnastics to "enable" Crowd in the
feature spec and this would sometimes cause a transient failure.

Really what it's testing is if the Crowd login form shows when Crowd's
enabled, so this is much better suited to a view spec.
