Fix an issue where we may "min()" an empty array when viewing a revision with no changesets

Browse source 
Summary:
Ref T13667. When a revision's diff has no changesets (usually because Diffusion performed an automatic update with an empty commit), the UI currently tries to "min()" an empty array and fatals.

Handle this case properly.

Test Plan:
  - Created a revision with a diff with no changesets ("git commit --allow-empty" + copy-paste into web UI).
  - Viewed revision.
    - Before: "min()" fatal.
    - After: UI isn't perfect, but works without fataling.
