[BUG] When using an int as state ID in reactor SLS stacktrace occurs

[Ch3LL]

Description
When a reactor SLS uses a int as the ID, I see this traceback in the master logs:

Steps to Reproduce the behavior
Start the Master and then the Minion. When the minion starts you should see the traceback in the log output.

Expected behavior
No traceback, but a clear error that you should not use int.
