ActivityScenario does not work with MultiDex on API level < 21

### Description
Hello,

I've noticed that ActivityScenario does not launch Activities when running MultiDex'ed applications on devices before API level 21.

### Steps to Reproduce
1. Use ActivityScenario
2. Enable MultiDex
3. Deploy on pre Lollipop device
### Expected Results
ActivityScenario launching Activity

### Actual Results
```
> Task :app:connectedDebugAndroidTest
Starting 1 tests on test(AVD) - 4.4.2
com.viliussutkus89.activityscenarioissue.ExampleInstrumentedTest > useAppContext[test(AVD) - 4.4.2] FAILED
java.lang.AssertionError: Activity never becomes requested state "[DESTROYED, STARTED, RESUMED, CREATED]" (last lifecycle transition = "PRE_ON_CREATE")
at androidx.test.core.app.ActivityScenario.waitForActivityToBecomeAnyOf(ActivityScenario.java:338)
Tests on test(AVD) - 4.4.2 failed: There was 1 failure(s).
```

### AndroidX Test and Android OS Versions
API levels 16, 17, 18 and 19.
```
androidTestImplementation 'androidx.test.ext:junit:1.1.3'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.4.0'
```
### Link to a public git repo demonstrating the problem:

Thank you for looking into this :)

Start with the linked ActivityScenarioIssue reproduction and the failure at ActivityScenario.java:338. Run its instrumentation test on a pre-Lollipop API level with MultiDex enabled, then compare the observed lifecycle transition with the expected activity launch. Done means ActivityScenario successfully launches the activity on the listed pre-21 API levels.
