* Allow _constructor_parameter_sets to return an empty
list. Implemented by Philipp Gortan. (GitHub issue #47)
* Error messages when Test::Class::Moose::Load cannot load a module
now include stack traces. (GitHub issue #43)

There's no need to explicitly delete it. We can trust dzil to regenerate this file as needed.
