Let's standardize usage of logs.

Few files have import static com.adobe.marketing.mobile.edge.identity.IdentityConstants.LOG_TAG;

I prefer IdentityConstants.LOG_TAG > import com.adobe.marketing.mobile.edge.identity.IdentityConstants.LOG_TAG

Not sure why this occurrence has a qualified import 😕 (because I did a replace all)!
I don't mind either way, but if I had to choose I would be inclined towards the static import as it is less verbose (especially when used a lot of time in the class) and also because it is an unambiguous import.

Looks good. Left a question for the test coverage, but feel free to take that in the tests PR
