Please update to espresso 3.6.0-rc01 or higher and fix BaristaIntents.mockAndroidCamera()

**Library Version:**

4.3.0

**Describe the Bug:**

In our app, we use espresso 3.6.0-rc01. Barista uses 3.4.0 it seems. As a consequence, the tests that use BaristaIntents.mockAndroidCamera() fail with:
```
java.lang.NoClassDefFoundError: Failed resolution of: Landroidx/test/espresso/core/internal/deps/guava/base/Preconditions;
```

It seems that this preconditions were removed, and now this [checks](https://github.com/android/android-test/blob/67a30ef587ced6c178eb20eebfc24c769c6daf7f/espresso/intents/java/androidx/test/espresso/intent/Checks.java#L19) should be used.

**Steps to reproduce the bug:**
1. Update espresso to 3.6.0-rc01
2. run a test that uses BaristaIntents.mockAndroidCamera()

**Expected Behavior:**

That no ClassNotFoundException is thrown.
