Remove PhanUndeclaredStaticMethod from blacklist

Remove PhanUndeclaredStaticMethod from blacklist

There was a single instance of this issue which was reasonably simple
to solve. The code that triggered the issue was not wrong, but calling
the grandparent constructor directly is not the cleanest code so it
seems right to fix it. Switch revision initialization into an
overridable function to remove the need to even have a constructor in
the class.
