Repo should not fetch tags for shallow projects
Repo should not fetch tags for shallow projects

Fetching all tags for a shallow git results in an
inconstent git and forces git to fetch more than
the depth specified.

This change teaches repo not to fetch any tags in a
repository initialised with the depth option.
