specFilter deprecation warning, although it's not used

[paulheising]

I have an Angular 7 project, and just upgraded the package.json to the latest versions of all dependencies. I wanted to verify that everything still works, and executing the unit tests, I get the following deprecation warning:

DEPRECATION: Setting specFilter directly on Env is deprecated, please use the specFilter option in `configure`

The tests succeed as normal.

The warning irritates me since I don't use specFilter anywhere in the project - at least not explicitely. Nor do I know, what this property exactly does.

Can someone help me out here?
