When a transaction has no quote ref, render "@user wrote:" properly

Summary:
Fixes T12576. In Javascript, `data.ref` is null, which is getting turned into `/quote/?ref=null`.

The code already handles this case, just not with `ref=null` happening in JS:

Test Plan:
{F4913862}

  - Also quoted a normal comment on a normal object in a normal way.
