[Assignment Enhancements] Assignment Enhancements broke comment continuity

Problem statement:

With Assignment Enhancements, comments on submissions are now only displaying separately in re-submissions rather than persisting as a continuous stream across a students' multiple submissions. This is problematic as it is several extra clicks for an instructor to access a previous comment to inform current grading on a new submission. It also makes previous comments less accessible to students, and any resources provided in a previous submissions comments are much less likely to be seen.

Proposed solution:

Return submission comments to how they functioned prior to Assignment Enhancements. Regardless of which submission is being actively viewed, ALL comments should appear in a chronological stream.
