Fix tests

Trying to fix.

Looks like some of the issues are from upstream commerce now. We'll have to check this more in deep.

@kul.pratap please use a separate MR to not break anything already working...

We need to get the pipeline green again, so other issues can be fixed with more confidence!
Setting priority to major for that reason.

Working on it.

@lavanyatalwar adding translations to tests is totally wrong (in most places), please revert these commits.
If you're unsure about changes you make, please use a separate branch for these changes to not pollute existing valid fixes!

Thank you.

Hi @anybody,

I apologize for the confusion with the recent changes. It looks like I misunderstood the requirements and implemented them incorrectly. I'll go ahead and revert the changes right away.

@rhovland: We should tackle this next together with 📌 Add Explicit Return Types and Discussion on Return Value Active
