Updated the maintainers phylesystem dummy repos

These are useful for testing phylesystem workflows, but they
were implemented before our id -> filepath mapping was
finalized.  This commit only affects testing code. It brings
the tests up to date with changes to
https://github.com/mtholder/mini_phyl
2d59ab892ddb3d09d4b18c91470b8c1c4cca86dc
and https://github.com/mtholder/mini_system
d43f6beb504a08b08b760f49589a54a00025a399

These changes make the test system a closer match for how
        we use the code in open tree web services.
