Editing a contact without an email type set fails even after checking the primary checkbox [8.6.0]

[eojedapilchik]

Issue

If you create contact with just the basic fields required, and do not tick anything on the email type, the contact is saved, but once you try to edit it again and save it, it throws a validation error. Even if you tick the email type as primary it fails.
It seems like validation is done on the previous dataset and not the staged or changed data of the contact, for the email field.

Expected Behavior

Once you specify the email type when it was not set previously you should be able to save it without having a validation error.
No validation error should show and block saving action

Possible Fix

As a workaround you can click on the More information and then on save.

Steps to Reproduce

1. Create a contact with just the first name, last name, email (but do not specify the email type, untick the primary)
2. Edit the contact and tick the primary checkbox in the email, and try to save
3. Validation error pops up

Context

Trying to save contacts after upgrade of SuiteCRM to 8.6, previous contacts did not have the email type set.

Your Environment

SuiteCRM 8.6 (upgraded from 8.2)
