Prompt when performing a submission with no grants

[emetsger]

Condition: a User exists for an authorized submitter, and there are Grants associated with their User. When preparing the submission, the preparer does not locate the User for the authorized submitter whatever reason. Instead, they provide the email address and name of the submitter.

A preparer may choose to enter in the email address and name of an authorized submitter instead of finding their existing User. As a consequence, the submission will be prepared with no grants (because there is no User, just Submission.submitterName and Submission.submitterEmail).

When the authorized submitter is notified, they login to PASS and are presented with the Submission Details page, with the option to Submit, Request Changes, Edit, or Cancel. Most authorized submitters will not carefully review the details, and simply hit Submit. Consequently, we have a Submission in the system that has no Grants, or associated Funders, or Funder policies. This affects where the Submission is deposited to, amongst other things. Generally speaking, it is in PASS's best interest to collect Grant information when possible.

It would be nice for the Ember UI to prompt the authorized submitter to assign a Grant before submitting. This may affect where the submission is deposited to, and what metadata are required. After attaching a Grant, the authorized submitter should have the option of delegating the submission back to the preparer, so the preparer can fill in any metadata, prior to sending it back to the authorized submitter all ready to go.
