Ensure First and Last Name are always set for user

Last name was dropped when editing user.
Corrected error in web front-end to account for recent code changes.

v-change-user-name will accept the following as valid inputs on the backend:
v-change-user-name $user "First Last"
v-change-user-name $user First Last
