ERR_STRING_TOO_LONG
**Description**
Tried to install a plugin this morning but Homebridge wouldn't do it. Searched in the log and got:
`Cannot create a string longer than 0xffffff0 characters`

Thought it was a Plugin Problem and tried other ones but failed as well.
After a bit of research that would be caused by a file larger than 256MB in the persist-folder, but checking that with ls -sh shows no file above 8KB.
