SVN diffs can contain entries for binary files that also introduce

property changes. We weren't handling these properly, skipping any

parsed files that contained property changes (with the assumption being

that they were standalone entries), but we don't want to skip them for

binary files.
This simply updates our logic to only skip for non-binary (standalone

proeprty) changes.

Unit tests pass. They failed without the fix.
Manually tested uploading sample diffs that were missing entries due to

the property change. Verified that all files were present and the diff was

correct after upload.
