[PDF] Fixes the cases where SkPDFDevice::finishContentEntry is called with empty content.
There are some cases (like drawing a completely transparent image) where the code tries to finish a content entry with no content and an xfermode other than clear. This makes those cases work correctly.
This is likely what was happening in chromium:316546, but it wasn't clear what the core problem was. desk_techcrunch.skp tripped a debug only assert that exposed the core issue.
