class not found exception

[mohamadk]

Description

Not sure why this is happening, but it looks like Leakcanaray cannot access a class in kotlin stdlib.
I checked the apk for both test and target both contain the class. 

Steps to Reproduce

sample project

Just run the UI test "mainActivityTest"

Expected behavior: [What you expect to happen]

Thanks for the bug report with a project that reproduces the issue. I was able to confirm the issue goes away when you add debugImplementation 'com.squareup.leakcanary:leakcanary-android:2.10', I didn't think to document this because projects are typically already using LeakCanary when they start adding leak detection in tests. Here's a PR that adds it: mohamadk/leakcanaryTest#1

I updated the docs: https://square.github.io/leakcanary/ui-tests/#getting-started
