How to test?

• Test all features described in the US. "fabiano" has no email anymore.
• This should also close
  • A system librarian without role librarian doesn't have all rights and has bugs #1340
  • The description of the user/patron street field should not ask for a coma. #1382
  • An e-mail without complete domain name can be saved in the patron editor #1381
  • Search by patron name and have an autocomplete in the checkin/checkout form #1364

Fixes needed after the tests:

• Renames PidAlradyUsed to PidAlreadyUsed exception.
• Changes the email validation message in several resources.
• Fixes update email value from the professional user editor.
• Adds a append option to the user creation script. This force to
  increment the PID counter and avoid error for new patron creation.
• Make the user email required when the librarian or system librarian
  role is enable.
• Fixes details document information display in the ILL requests of the
  patron profile.

• patron public account: the first ILL request cannot be expanded (stay collapsed). I don't know if it is linked to this PR.
  
• create users: not able to save a new user, it spins forever. Updating an existing user works!
• create users: if the e-mail is required for librarian, is it possible to have a warning or a description text?
• create users: a default expiration date should be set (current date + 3 years)
• create users: the validation message for e-mails that don't match the pattern is too complex. It should be just "The e-mail is not valid."
  
• create users: when I remove the e-mail of a patron in the pro user resource, this patron can still login with this e-mail. When I replace it by another e-mail, the patron cannot login with the new one, but still with the old one. For info: when I change my e-mail in the RERO ID, this works!
• checkin/checkout: in the checkin form, it spins forever when I search for a word that is only present in a non patron user (example: search for "astrid", search for "rodriguez"). This is not blocking.
