Mutable defaults are generally bad, so thought it would be okay to change this

| if a is None: | ||
| return b | ||
| assert b is not None, "Merge requires at least on non-empty Individual" |

Does this follow the intention here?

| from pymoo.core.problem import Problem | ||
| problem = Problem() | ||
| # TODO: this line is probably never evaluated. It would raise as Problem is ABC |

Is it necessary to assign None to these, or could they be empty as in reset below?

Issue #665
mypy now passes when run on
core.algorithm. I tried to avoid changing anything substantial. The tests are passing to the same extent as inmain.Because I was avoiding changing anything too much, there are a lot of ignore statements (there's only so much one can do with annotations).
