The status command fails when a repository has no tag

[pomek]

📝 Provide detailed reproduction steps (if any)

1. Create a mrgit.json configuration file containing a repository with no tags.
2. mrgit sync
3. mrgit st

✔️ Expected result

No errors.

❌ Actual result

• An executed command for collecting the status ends with error: fatal: No names found, cannot describe anything.
• The table status does not contain the repository.

❓ Possible solution

If a repository has no tags, we should not match anything. Not sure it helps 😄

Also, another case. If the repository uses the @latest tag, but there are no tags, it should not blow up. Instead, use the default branch and print a warning that the @latest tag could not be matched because the repository does not have tags.
