t6500: use "ls -1" to snapshot ref database state

Browse source 
By doing ls -1 .git/{reftable,refs/heads}, we can capture changes to both
reftable and packed/loose ref storage.

This relies on the fact that git-pack-refs (which we're looking for here)
changes the number (loose/packed storage) and/or names (reftable) files used for
ref storage.
