Add clear storage between tests function

[pochikaevams]

1 The issue is there is no good solution to clear storage data while running tests
2 Would be great to have box based function to call before any tests (or all of them), to remove all data after previous tests
3 Alternatives:

• Marathon
• fun clearStorage() {
  InstrumentationRegistry.getInstrumentation().uiAutomation.executeShellCommand("pm clear PACKAGE NAME")
  .close()
  }

Seconded 👍 ,
An inbuilt helper for this would be great.

pm clear is awful solution. Clear shared, internal and such in before hook, if needed use hilt injection to clear other stuff. pm clear breaks instrumented tests instantly when run.
