fix(api): preserve file extension in upload-from-url endpoint

Browse source 
The upload-from-url endpoint passed an empty originalname to
uploadFile(), causing extname('') to return '' and files to be saved
without an extension. Derive the extension from the response
Content-Type header (or URL fallback) so files are stored with the
correct extension on disk.

Fixes gitroomhq/postiz-app#1147
