Description of problem:

When more than one instance of a system unit exist, systemctl reload does not reload all of them, but only the one started last.

Version-Release number of selected component (if applicable):

systemd-219-19.el7_2.12.x86_64

How reproducible:

Always

Steps to Reproduce:
1. create a systemd unit, and a systemd template with an ExecReload option
2. start the main unit and then start one instance from the template
3. try to reload both of them with "systemctl reload myservice\*"

Actual results:

systemd will reload just one services, but twice.

Expected results:

systemd should reload each service once.
