Description
When Uploading an empty file through the REST API (POST to /uploads.json), the response is 201 Created, and an invalid token (which that does not resolve to an attachment through Attachment.find_by_token because it lacks the digest component) is returned. However an attachment record is still saved, but without a corresponding file in the file system.
When looking into this I found that the easiest fix for this would be to change the two conditionals in attachment.rb that prevent an empty file from being treated like any non-empty file. I don't see any technical reason to not allow the uploading of empty files, and my change doesn't seem to cause any of the existing tests to fail.
Attached is a patch which does that, including a test case illustrating the inconsistent API behavior I described above.

Fixes uploading of empty files (#25115).
- prevents creation of attachment records without existing diskfile and empty
digest
- adds test case to check file upload API response
- also removes the file size check in ActsAsAttachable which still prevented
attachment of zero size attachments to containers but only for clients
without Javascript (where save_attachments is called with the actual file
upload).

Here's an extended version of the patch. This one also removes the file size check in acts_as_attachable which prevented empty attachment creation for http uploads without javascript (in all other cases this part of the code isn't relevant since save_attachments is called with just the tokens of already saved attachments).
This patch replaces the original one.
