Dashboard is slow to display with nested groups and LDAP

The dashboard can be extremely slow to render if nested groups are enabled with an LDAP repository. It needs to be improved so that it works almost as quickly as when nested groups are not used.

This issue only affects Confluence 3.5 - 3.5.4. It is resolved in Confluence 3.5.5
