Fix failing test in Mypy 1.6.0 (#296):

Since Mypy 1.6.0 changed how tuple types are printed, the check that depended
on the old behavior broke. The current method I am using is already a
workaround because I cant get Mypy's built-in type system working with Refurb,
though perhaps I should give it another try soon.

Closes #295
