coalesced locations are counted multiple times

Created by: sqs

Repro:

1. Go to https://sourcegraph.com/github.com/pallets/flask@d5665e4ba6cf4f7eabdc0be047952a27965a455f/-/blob/flask/debughelpers.py#L27:2&tab=references
2. Ensure that fuzzy matches are shown
3. Note that the counts are 4 and 3 for the 2 files on the left

The counts are incorrect. basic-code-intel's fuzzy matches and the Python extension have the same locations as results. They are coalesced in the list of locations with snippets, but the count badges double-count the matches.
