Only hosts that have a primary nic assigned to a domain should be counted in the domain host count. Previous implementation was flawed in that it only updated the counter in certain occasions and not all, leading sometimes to incorrect host counts. I have implemented the counter updates in `after_commit` to reduce chance of deadlocks.
