The run-router.sh file should check for an existing router

[gberl002]

The exact process to replicate is not known for certain, however, here are what are believed to be the reproduction steps.

1. start router
2. stop router
3. rm persistent files
4. start router
   fails (because router exists in openziti)

then:

1. deleted the router in openziti
2. start router
   fails because enrollment was invalid, but the access-control.init file exists or something? (didn't really dig in)

then:

1. delete router in openziti
2. rm persistent files
3. start router
   success
