Description:

When we use a Flowable to get an update notification after inserting a new data-base row, works fine.
But when the insertion is done inside another explicit transaction, the Flowable does not get a notification.

- Sample project to trigger the issue.
To illustrate the issue, I've forked the BasicRxJavaSample from android-architecture-components and added 2 test-methods to UserDaoTest.java:
https://github.com/tmtron/android-architecture-components/tree/master/BasicRxJavaSample

see failing test: testFlowableInTransaction
https://github.com/tmtron/android-architecture-components/blob/master/BasicRxJavaSample/app/src/androidTest/java/com/example/android/observability/persistence/UserDaoTest.java#L84
