Dead link in Account settings (BB-5141)

On the "Change username" tab of the Account settings, inside the rename warning, the words "Renaming this account" link to:
http://confluence.atlassian.com/x/tQF7DQ

Which has since been deleted - it should probably be updated to:
https://confluence.atlassian.com/display/BITBUCKET/Renaming%2C+Converting%2C+or+Deleting+an+Account#Renaming,Converting,orDeletinganAccount-RenaminganAccount
