attempt at having users#preferences to redirect to modal if no email add...

trying to test the preferences, and getting this error:

  1) UsersController GET 'preferences' if user does not have email saved should render email update partial
     Failure/Error: expect(response).to render_template partial:'welcome/modal'
       expecting partial <welcome/modal> but action rendered <["welcome/_modal", "_modal"]>.
       Expected {"welcome/_modal"=>1, "_modal"=>1} to include "welcome/modal".

Occasionally, I'm getting the entire user profile to render in the modal popup itself, which is strange.  Not entirely sure how to call the modal to update email address.
