Steps to reproduce:
1. Set up a project using the 2.1.0-beta01 version of the Sqlite Android X library
2. Create a ContentProvider
   a. When configuring the database in the ContentProvider, set the builder to use the noBackupDirectory. E.g. SupportSQLiteOpenHelper.Configuration.builder.noBackupDirectory(true)
   b. In the ContentProvider's shutdown method, call close on the database
4. Create a test case using ProviderTestRule
5. Run the test case

Results:
Expected: The test case completes without any issues.
Actual: The test case fails because the database can't be closed since the DelegatingContext throws.  Example stacktrace below:
