[Fix][7323] Character Customize should not force rename

[Auntie Mangos]

* What bug does the patch fix? What features does the patch add?

This patch makes it so that character customization (from AT_LOGIN_CUSTOMIZE) does not force you to rename. At the moment, if you leave your name the same, it will give you the error message that a character with that name already exists.

* For which repository revision was the patch created?

For Revision 7276

* Is there a thread in the bug report section or at lighthouse? If yes, please add a link to the thread.

There is a bug report for this, see : http://getmangos.eu/community/viewtopic.php?id=6341

* Who has been writing this patch? Please include either forum user names or email addresses.

Just me.

Thanks, sometimes I erroneously rename myself instead of target and I'm forced to rename at login to another nickname.
