Same reference appears twice (with commit specified and unspecified)

Created by: dadlerj

• Sourcegraph version: alpha9

Steps to reproduce:

Haven't tried to repro on another repo yet.

1. Follow the instructions here: https://github.com/sourcegraph/sourcegraph/issues/1717
2. Go to http://localhost:7080/github.com/sourcegraph/sample-public-go-repo/-/blob/main.go#L5:25&tab=references
3. Ensure that:

• Fuzzy matches are turned OFF
• Show references from other repositories is turned ON

Note that you see two references to the same line. If I "Hide references from other repositories", the 2nd one goes away.

If I click, the two URLs I get taken to are:

• http://localhost:7080/github.com/sourcegraph/sample-public-go-repo@1d29938eca9afab8e8a26479d78e60b5978c0f57/-/blob/main.go#L5:25
• http://localhost:7080/github.com/sourcegraph/sample-public-go-repo/-/blob/main.go#L5:25

The extension seems to think the specified commit is a different repo.

Expected behavior:
