Fake ServiceInfo doesn't contain processName, causing LeakCanary failure

[Egorand]

Description

Unit tests ran with RobolectricTestRunner fail with the following exception:

java.lang.NullPointerException
	at com.squareup.leakcanary.internal.LeakCanaryInternals.isInServiceProcess(LeakCanaryInternals.java:114)
	at com.squareup.leakcanary.LeakCanary.isInAnalyzerProcess(LeakCanary.java:182)
	at com.squareup.cash.CashApp.onCreate(CashApp.java:45)
        ...

The stack trace points to the following code in LeakCanary codebase:

ComponentName component = new ComponentName(context, serviceClass);
ServiceInfo serviceInfo;
try {
  serviceInfo = packageManager.getServiceInfo(component, 0);
} catch (PackageManager.NameNotFoundException ignored) {
  // Service is disabled.
  return false;
}

// this line causes the crash
if (serviceInfo.processName.equals(mainProcess)) {

Debugging shows that the value of processName is null.
