flux fails to find tags in airgap

Issue came up in the T3 where flux is unable to clone the tags needed.

Example error:

bigbang     monitoring           ssh://git@10.25.10.243/home/git/repos/monitoring           False   unable to clone 'ssh://git@10.25.10.243/home/git/repos/monitoring', error: unexpected client error: reference not found   76s

Current workaround is to enter the local repo folder and run a git checkout of a branch.

Issue did not seem to exist in 1.2.0 so it's very likely that the issue was introduced by one of the MRs that modified packaging in 1.3.0 - (see https://repo1.dso.mil/platform-one/big-bang/bigbang/-/merge_requests/327/diffs)

Any resolution will require a patch on the 1.3.0 release and should be included in all future releases.
