File Size Not Always Correctly Reported

[BenGalewsky]

Problem

The total_bytes property of the FileCompleteRecord comes out of the stats reported by the generated code. This is not always provided, and it's hard to test and fix each of these.

Approach

The most correct way to report the size of the file is to just ask the operating system. Use the python Path,getsize call to get the correct information to report to the app.
