Broken link to attachment in JIRA Service Desk notification

As per JSD-43 and JSD-338, attachments from JIRA issue view needs to be embedded in a comment in order to have the attachment accessible from Service Desk.

Whenever we embed the attachment in a comment, JSD notification will be triggered containing the body of the comment, with the link to the attachment.

However if we embed the attachment in the "Attach Files" dialogue, the attachment link in the notification is broken.

Step to reproduce, on a Service Desk enabled project:

• In the issue view, go to More Actions -> Attach Files
• Add a new attachment
• In the same dialog, embed the attachment, eg: [^attachment.ext]
• After receiving the notification, try to open the link to the attachment. You'll find that the attachment link is broken

Example 2:

• On an existing issue with attachment
• Go to More Actions -> Attach Files
• Embed the existing attachment in the comment field, eg: [^filename.ext]
• After receiving the notification, try to open the link to the attachment.

Conclusion: When we embed an attachment via the Attach Files dialogue, the link to the attachment in the JSD notification is broken.
