Fix for case of inherited from Test tasks with own executers

[zhurs]

Now plugin relies on task executer class, but this approach don't work with inherited tasks with own executers, for example with Kotlin Multiplatform Tests.

There are some issues for this problem:
#116
#140

Possible solution is to store last result outside of the retry executer.

@zhurs Could you please elaborate how this fixes the integration issue with KMPP? As far as I can tell, there would be multiple instances of the KMPP TestExecuter implementation created so the structure would be KotlinJvmTest$Executor(RetryTestExecutor(KotlinJvmTest$Executor(...))), wouldn't it?

[zhurs]

@marcphilipp You are absolutely right.
But KMMP executer just add "[jvm]" suffix to the test names, after fix suffix will be added twice - it is not very good, but at least retry will work correctly.
I don't see better way to fix issue ;-(

On the other hands fix itself is not bad - it just remove requirement of specific executer class, it will work with other Executer delegate-chains.

Can this be revised?

@marcphilipp do you have a better solution in mind to address the original problem with test runner in Kotlin MPP projects?

If so could you please share the plan when they will be properly supported.

We don't have a clear roadmap for it yet. This is a common request (also see #116), so we'll take it into account when planning the next set of features for this plugin. Unfortunately, I don't have more to share at the moment.
