Merge branch 'release/0.9.4' into develop
Make FileFile.get_file_name cope with sitiuations where self.file.name is not set.
This is quite an often situation: an user uploads a file to filer it doesn't set the name explicitly, therefore the original_filename is used.
Use the file's storage to determine whether the file exists or not.
The existing implementation that uses posixpath.exists only works if the storage backend is the default FileSystemStorage
Reverted change to get_file_name; that's already covered by a different changeset
