invalid email address for a profile

Some datasources (for example `mbox`) return an anonymized email of the contributor shorting it adding a `...`, which makes it an invalid email.


With `jira` datasource, sometimes we get the email in the form: `name dot something at domain dot com`:

May happen that we store those invalid/anonymized emails while we have another valid emails from other identities/datasources in the same profile (individual). So we should save as main email of the individual a valid email instead of an invalid/anonymized email address.
