Incorrect error message on cloning unauthorized repo

[jescalada]

Describe the bug
When cloning a repo that isn't in the authorisedList or in the repo database, an incorrect/unrelated error message appears.

To Reproduce
Choose a repo that isn't in the authorisedList or in the repo database, then clone it:

1. Run GitProxy
2. Execute the following (replace with invalid repo)

git clone http://localhost:8080/open-webui/open-webui.git`

This gives the following error:

fatal: http://localhost:8000/open-webui/open-webui.git/info/refs not valid: could not determine hash algorithm; is this a git repository?`

Adding the repo to the database or authorisedList will let the clone go through (therefore the command is correct).

Expected behavior
This flow should display a relevant error, such as REPO_NAME not in authorisedList or database.

Is that from after #1164 was merged?
