Fix projection query field mapping issue

When using projection queries with entities that have @Attribute annotations
for LDAP field mapping, the query was using Java field names instead of
the mapped LDAP attribute names. This caused queries to fail when the
Java field name differs from the LDAP attribute name.

Changes:
- Modified LdapQueryCreator to map projection fields using
  ObjectDirectoryMapper.attributeFor() method
- Updated test assertions to verify correct LDAP attribute names
  are used in queries (e.g., "sn" instead of "lastName")

Example: For an entity field 'groupId' mapped to LDAP attribute
'gidNumber' via @Attribute annotation, projection queries now
correctly use 'gidNumber' in the LDAP query.

Fixes projection queries for entities with custom LDAP attribute mappings.
