Integration Test Fix

[mpierucci]

It seems there is a bug in the coroutine test library that prevented testing suspended functions with external thread management.

• runBlockingTest raises job has not completed yet with Futures Kotlin/kotlinx.coroutines#1395
• runBlockingTest fails with "This job has not completed yet" Kotlin/kotlinx.coroutines#1204

This in conjunction with the suspendCoroutine implementation opted by this project ( to make callback Retrofit call API into coroutine friendly) broke Integration tests capabilities.

Kotlin/kotlinx.coroutines#2978

Looks like something that could fix that, so once released check it out and re-enable integration tests.

PS: It also forces repository unitest to run with runBlocking which is bad if delays and such start being implemented
