kotlinx.coroutines.test compatibility

[sergeych]

New kotlinx.coroutines.test provides smart and convenientrunTest {} implementation, that provides sort of vurtual time, "eating" delay() calls and advancing "system" time accordingly, also providing advanceTimeBy(duration) convenienct method.

Clock.System.Now() as for now is not compatible with it so testing anything that uses kotlinx.datetime provides severe and hard to understand test-time bugs.

There's already a PR that would solve this that we're not sure about: #164

Do you maybe have some use cases not listed in #164 (comment)?

I'll try it, thank you.
