Fix an issue where inlines could be duplicated in the client list

Summary:
Ref T13559. D21261 added caching here, but the logic in rebuilding inlines wasn't quite correct, and could lead to us double-appending.

Instead, when rebuilding, unconditionally discard the old list.

Test Plan:
  - Added inline comments to a file in Differential.
  - Marked some done.
  - Scrolled so the inline comment header was visible, saw "X / Y Comments" button in header.
  - Clicked "Show 20 more lines" on the changeset with inlines (or toggle "View Unified" / "View Side-by-Side", or other interactions likely work too).
    - Before: saw "X / Y" change improperly (because inlines in that file were double-counted).
    - After: saw stable count.
  - Grepped for "differential-inline-comment-refresh", got no hits, concluded this event has no listeners.
