Dolt clone on tag name results in multiple issues

[farhanhubble]

Reproduction:

1. On doltlab create a new tag via the "Create Release" flow, say "tag-01"
2. Clone only this tag dolt clone origin "tag-01" <doltlab_url>
3. Try dolt status
4. Try dolt branch -v
5. Try dolt log
6. Try dolt sql -q 'select * from dolt_branches'

Current behavior:
Commands 3,4 result in unexpectedly received non-string column in 'SELECT active_branch()': %!s(<nil>). Command 5 results in this operation is not supported while in a detached head state while command 6 results in no branch data.

Expected behavior:
Either dolt clone should not work with tag names or it should leave the repo in a state where basic commands work

Dolt version: 1.43.0

Thanks. We need to copy some of the Git behavior here.

Hey @farhanhubble, thanks for reporting this issue.

We've improved our error handling for tags. You shouldn't be able to reference a tag in dolt clone.

dolt clone --branch tag1 <dolt-repo-url> db

Should throw an error.

We'll have a release with these changes out later this week!
