split-screen mode: NullPointerException crash in UploadMediaDetailFragment

[psh]

Summary

I am unable to double-check that I have the correct photos to upload (by using split screen with the photos app) because it causes a NullPointerException every time.

Steps to reproduce

1. Select a couple of pictures in Google Photos
2. Share them with the commons app
3. Go into split-screen mode and select the photos app

Expected behaviour

The app should not crash

Actual behaviour

The app (reliably) crashes with a null pointer exception
