Fix plugin remove issue

[Jule-]

Like discussed with @briantq in #898, this PR should be harmless but need other people to test it in their projects.

Ok maybe we can't move <framework /> dependencies for old cordova version...

EDIT: to be confirmed

@briantq I think I know why there is a dummy google-services.json... For test build to succeed I think...

By the way it seems like tests are somehow broken because build fail for cordova 8.0.0 and it is detected as success:

Plus I don't have issues building on my environment with com.android.tools.external.com-intellij:intellij-core:26.0.1.

Ok issue in cordova-android@7.1.0 fixed in cordova-android@7.1.1, see https://issues.apache.org/jira/browse/CB-14127.

So it is working just need to wait new release cordova-android@7.1.2...

Just saying but cordova-paramedic project looks promising in order to externalize CI boilerplate stuff and write automated tests!

@soumak77 might want to weigh in on the CI suggestion. I have not touched that area yet. I have been pretty slammed with my day job but hope to catch up on code reviews this weekend.

@briantq tests are working now! Thanks to cordova-android@7.1.2 release as expected. Could you please merge this PR now?
