check_repository_format_gently(): refuse extensions for old repositories
Previously, extensions were recognized regardless of repository format
version. If the user sets an undefined "extensions" value on a
repository of version 0 and that value is used by a future git version,
they might get an undesired result.
Because all extensions now also upgrade repository versions, tightening
the check would help avoid this for future extensions.
