Bug 15632: Koha::Patron::Messages - Remove GetMessagesCount

The GetMessageCount subroutine was only used once, in opac-user.pl, to
know if some messages will be displayed.

Test plan:
1/ Create messages to display at the OPAC for a patron
2/ Logged this patron in at the OPAC, you should see the messages
displayed.
