mock untyped parameters

[ivyhjk]

some classes are already written in PHP, and when their have some untyped parameters, mocking fails, for example:

<?hh // decl

class Foo {
  public function untypedParameter($param): void { 

  }
}

also works with <?php as initial tag.

The error:

Fatal error: A type specifier is expected here. in /app/vendor/usox/hackmock/src/Mock.hh(123)(df9b58dfc07696f2f66f85fd021ce9e7) : eval()'d code on line 5

I know that PHP support is ending for HHVM, but come on, this is breaking a lot of possible mocks and possible integrations with this great library.

I think, I'm ok with it. I actually don't remember, why I had to add the leading ? in the first place. After performing some tests with some of my projects, it indeed seems to be unnecessary.

Thanks!
