Agree, I think we should surface this error to users when the index is stale or 
we don't have enough confident to perform the rename.

Thinking more about this -- we have a dynamic index (for all opened files) 
which is overlaid on a static index (which is a background index in open-source 
world), so for all affected files, they are either in

1. an open state -- we can rely on the dynamic index, I think it is safe to 
assume that index always returns up-to-date results;
2. a non-open state -- rely on the background index, however background index 
has more chance to be stale (especially we don't detect file-change events at 
the moment), we could do a range patch heuristically to mitigate this stale 
issue. Failing that, we surface the error to users.
