Grant Permissions Rule errors out while connecting to UiAutomation

I keep getting these errors for few of my automation tests. Most of the times, on re-running the tests, it works fine again

```

I am granting permissions in the following manner

```
public GrantPermissionRule grantPermissionRule = GrantPermissionRule.grant(Manifest.permission.WRITE_EXTERNAL_STORAGE, Manifest.permission.READ_PHONE_STATE, Manifest.permission.READ_EXTERNAL_STORAGE);
```

Any help in this regards will be appreciated.

Beginne damit, den sporadisch auftretenden Fehler rund um GrantPermissionRule.grantPermissions und den Stack Trace von UiAutomation.connect mithilfe der im Issue gezeigten Berechtigungsdeklaration zu reproduzieren. Verfolge den Aufruf von BaseTest.java:40 über PermissionRequester und UiAutomationShellCommand hinweg und ermittle anschließend, warum ein erneuter Versuch manchmal erfolgreich ist. Als erledigt gilt die Aufgabe, wenn die Ursache festgestellt ist und die Einrichtung der Berechtigungen nicht mehr sporadisch fehlschlägt.
