Changing the collation from latin1_swedish_ci to utf8mb4_unicode_ci

[delageniere]

For some data imported from the User Portal DB at ESRF, we need to change the collation of the column. For example: Person.phoneNumber.

As a more general issue, I am wondering if we should better update all the string collation with utf8mb4_unicode_ci ?

I updated also Person.familyName, Person.givenName and LabContact.cardName
