fix(core): mails_namespace attributes now extend userVirtualAttributeCollectedFromUes

Description

fix(core): mails_namespace attributes now extend userVirtualAttributeCollectedFromUes

- changed attribute modules mails_namespace:(microsoft/google)

- modules now correctly trigger propagations on relevant changes

How to test

• Find some set up service (e.g. generic_json_eduvpn) and set the mails_namespace_microsoft attribute as required for that service
• Set yourself (or any other user) as a member of one of the groups from the resources of the service's facility (e.g. jo test group) and be careful to have a valid status as both Vo and Group member
• Set to yourself (or your test user) an identity with microsoft external source
• Set the ues attribute mail to your microsoft identity
• See if the service run is triggered on the facility services status page of your service

You can try the same for the google attribute module.
