Revert 235752 "Fix chrome upload with content uri"

> Fix chrome upload with content uri
> 
> For android, the upload file dialog returns files with content uri scheme(content://).
> This CL makes it possible for upload to work with this new file type.
> It fixes both the form and fileapi based uploads.
> 
> The CL follows the same code path used by regular file upload and the content url is encompassed by a FilePath object.
