"afm-util run" only works once for a particular app

This might be a lack of understanding of what afm-util is supposed to do, but I'm trying to implement a test case where applications are switched in different orders, and "afm-util run" will only start an application the first time.

For instance, if I run `afm-util run hvac@0.1`, and then `afm-util run radio@0.1`, both of these operations work, but running `afm-util run hvac@0.1` a second time has no effect.

After observing this I thought perhaps `afm-util continue <id returned by run>` might be the correct way to do this, but it reports "Operation not supported"
