Address Rendered Message When 'Feedback Request' is Successfully Sent on a Plan

[aaronskiba]

Please complete the following fields as applicable:

What version of the DMPRoadmap code are you running? (e.g. v2.2.0)

• v4.1.1

Explanation
Rather than receiving a generic success message, the rendered notice is a copy of the feedback request message.

• 

I'm not sure exactly if or how we should address this. Maybe the success message notification can be kept, but the Your plan "{plan_name}" has been submitted... message rendered within the body of the page (see below image) should be removed?

    # Use the generic feedback confirmation message unless the Org has
    # specified one
    text = current_user.org.feedback_msg || feedback_confirmation_default_message
    feedback_constant_to_text(text, current_user, @plan, current_user.org)
