Rebuild doesn't check alias for parent_id

[sahamilton]

v2.x-dev Rebuild fails with message
Illuminate/Database/QueryException with message 'SQLSTATE[42S22]: Column not found: 1054 Unknown column 'persons.parent_id' in 'where clause' (SQL: select count(*) as aggregate from personsleft outer joinpersonsAS parent onpersons.parent_id = parent.id where (persons.lftIS NULL ORpersons.rgtIS NULL ORpersons.lft>=persons.rgt OR (persons.parent_id IS NOT NULL AND (persons.lft <= parent.lftORpersons.rgt >= parent.rgt))) and persons.deleted_at is null)'

where the model (in this casePerson) has an alias for the parent column:
protected $parentColumn = 'reports_to';

OK My bad ... Looks like the parent column name has changed to parentColumnName vs parentColumn in prior version...
