Summary:
Import/export to/from a document picker extension works, if the document picker extension is backed by a file provider extension. However, if there is no file provider, then often (but not always), import/export will fail with an alert view with the following:

Failed to make file available
The file could not be made available to the application. (The operation couldn't be completed. (BRCloudDocsErrorDomain error 10.))

Steps to Reproduce:
1. Create an app that contains both a document picker and file provider.
2. Use the same app or a different app to choose a file from the document picker.
3. Now delete the file provider completely from the app, and recompile and reinstall it.
4. Use the same app or a different app to choose a file from the document picker.

Expected Results:
2. The file is successfully chosen and passed back to the host app.
4. The file is successfully chosen and passed back to the host app.

Actual Results:
2. The file is successfully chosen and passed back to the host app.
4. The file is occasionally (but rarely) successfully chosen and passed back to the host app. Usually, a modal alert view is displayed:

Failed to make file available
The file could not be made available to the application. (The operation couldn't be completed. (BRCloudDocsErrorDomain error 10.))
