Merge #6112

6112: Add a spec for installing git deps after packaging without git r=deivid-rodriguez a=segiddins

### What was the end-user problem that led to this PR?

The problem was v1.15 seemed to break installing without git when the git deps had already been packaged (see #6066).

### What was your diagnosis of the problem?

My diagnosis was we actually seemed to have fixed this for 1.16.

### What is your fix for the problem, implemented in this PR?

My fix adds a test to ensure we won't regress.
