Version of this package at public-repo (0.8) crashes

[brobertson]

If you install exist-db 5.1 and then follow the packagemanager to install AtomicWiki 0.8 available there, clicking on the package gives this error:

HTTP ERROR 500 javax.servlet.ServletException: javax.servlet.ServletException: An error occurred while processing request to /exist/apps/wiki/: err:XPST0003 error found while loading module login: Error while loading module modules/login.xql: Syntax error within user defined function login:set-user: unexpected token: ( [at line 48, column 38]

This is because of the function return type empty(), which I note has been replaced with empty-sequence() in the code submitted to git-hub 3 months ago.
