Bug 23199: Koha::Patron->store must check 'uppercasesurname' syspref

Test plan:
1/ set uppercasesurname to 'Do'
2/ register a new patron using the REST API with lowercase surname
3/ verify the surname is not saved in uppercase
4/ apply patch
5/ repeat 2
6/ verify the surname now is saved to uppercase
