Issue On User Account Form

Hello,

I have issue on user account form which make me cannot save a user account page unless I change the unique field value, which is wrong because there is no duplicate value elsewhere.

Steps to reproduce

1. Create a field at admin/config/people/accounts/fields
2. Set the field as unique field at /admin/config/people/accounts
3. Edit a user account and set value to the field & Save.
4. Edit another user account and set value to the field (uniquely) & Save
5. Edit any user account & simply Save (doesn't change any field value, just save)
6. Error message appear "The field field_xxxx has to be unique" which is wrong because there is no other user account has the same value.
