[Bug]: detect common config errors

[procodix]

Expected Behavior

I think it is a catchable mistake, if script categories are not configured. They could be simply ignored, logged, or shown under an auto-configured category.

Current Behavior

the JavaScript console shows cryptic (compressed JS) messages about null types ("s.xe").

Steps to reproduce

include a script with a data-category="something", and configure a category with a name of "different".

Proposed fix or additional info.

No response

Version

3.0

On which browser do you see the issue?

Firefox, Safari

Yes, they should be ignored as in v2.
