Name validation in consent and UP name

[robertsamm]

A bug was found in prod where a UC participant entered 'n/a' on the consent middle name screen but can't move forward to submit on the User Profile.

@JoeArmani did some investigating, and found a bug where the consent doesn't have middle name validation but the UP does which is preventing them from submitting the UP. The symbol "/" is preventing them from moving forward. The prod participant signed up with a new account and was able to move forward so we will not need to fix the issue for their account, but we will need to fix the validation so this does not occur again for other participants.

The name validation should be consistent between first, middle, last in both the consent name fields and the User Profile name fields.
