Feels like expected_headers and expected_body should move into 
_FileHandlerHelper. May need to change how the body gets consumed here and
PostOnlyFileHandler to make that work. 

Another thought for these tests - could you just use the EchoAllHandler instead?
Might need to modify it to report the method used.

Done.
The downloads extension api does not provide any way to access the contents of
downloaded files.
I'd rather not depend on an unrelated API such as the HTML5 File api unless
absolutely necessary in case that API changes, and so that I don't have to
figure out how.
