Certain $GLOBALS['project'] dependent URLs break when it's not present

[matamouros]

[Reported by Miguel Manso]

Problem:
Certain URLs that depend on $GLOBALS['project'] might get broken when that global var is missing, i.e., when a URL is copied/pasted on an empty session.

Reproducing steps

1. Logout
2. Go to url http:///project/history

Result (probably not necessary)
