Add unit test for CXFA_FileRead.
The FileRead's return convention is being modified at https://codereview.chromium.org/2430743003/, so first provide a test of the old behaviour. Fix some issues with null dictionaries as provided by the CPDF_Stream default ctor along the way. Review-Url: https://codereview.chromium.org/2517513003
