sparse-checkout: add sanity-checks on initial sparsity state
Most sparse-checkout subcommands (list, add, reapply) only make sense
when already in a sparse state. Add a quick check that will error out
early if this is not the case.
Also document with a comment why we do not exit early in `disable` even
when core.sparseCheckout starts as false.
