One of the layers we've torn down has torn down the db fixture object,
it shouldn't have. Its possibly/probably tied into my workaround for
FunctionalLayer et al not being tear-downable.

We could either put a priority on fixing FunctionalLayer etc to be
teardownable, migrate from layers more quickly, or put a hack (with a
logged warning please to resetUp just-in-time).
