Issue comments are not updated after editing (if attachments are disabled)

[ukct]

Description

Attempting to edit a comment and then save it results in a javascript error withn repo-issue-edit.js, if attachments are disabled.

To reproduce:

• disable support for attachments
  (https://docs.gitea.com/administration/config-cheat-sheet#issue-and-pull-request-attachments-attachment - set enabled to false)

From the UI:

• create new issue
• add a comment
• edit that comment
• saving the edit will throw a javascript error in the saveAndRefresh method in repo-issue-edit.js, when attempting to iterate through dropzoneInst

This appears to be a new issue introduced in 1.22.
