Potential Phantom devices remained around when changing hub name
**Describe the bug**
When I changed the name param, I noticed that phantom devices hung around that were associated with old settings using the other name!

**To Reproduce**
Create an instance not using the new TV remove settings where all devices get listed. Add devices in home app.

Then change the json name param to use a new name, and only use the simple TV mode settings.

When I re-add homebridge  in the home app  I see both new remote UI AND all the old devices that are associated with the old name.

Removing the persist file and cleanCache were not enough. I had to delete ALL the files in the homebridge directory that started with the names: harmonyPluginNames_* and use cleanCache for thing to get fixed up.

Not sure if easy to fix, but improved instructions are warnings about changing names might be advised.
