change collectJob to backgroundScope coroutine

[saeedishayan76]

Hello,
‌Based on the latest document available in developer.android, we can use backgroundScope to collect flows instead of making a job object and canceling it after the final assertion.
With that, we do not need to manually cancel the created job, and the cancellation of this coroutine is done automatically before the end of the test. The following links are about the example on the site of developer.android and kotllinlang:

I'd also tried that approach before, but I've got fail on unit tests.
Did you pass the unit tests on this PR?

Thank you for making these changes! I think this definitely helps improve the readability of these tests.
