Remove more ldap project references

Commit I848bf41022224fec65cd9555a6e82790b296dcbe removed the
LDAP resource and assignment backends. As a result, some more
items can be removed, namely:

* ProjectLdapStructureMixin class is no longer used anywhere.
* references to project related ldap attributes in test conf files
* removal of references to ldap project attributes in configuration
