Cannot pass a list of tags

[tobiasheine]

Passing a list of tags like in ./gradlew connectedCheck -Ptags="@foo, @bar" doesn't work.

com.android.builder.testing.ConnectedDevice > No tests found.[Nexus_5X_API_23(AVD) - 6.0] FAILED No tests found. This usually means that your test classes are not in the form that your test runner expects (e.g. don't inherit from TestCase or lack @Test annotations).
