fix(chips): interaction with Autocomplete

[typotter]

Properly set require-match=true in demos so that the value is correct in the components.
Check for requiredMatch on the controller instead of on the scope.

fixes #3475

@robertmesserle Now that you are on a PR streak, maybe this one could make it as well? :)

Thanks a bunch. I tested and it all works well, as long as you make sure to get md-require-match="true" set.

Yea, this is a known issue that I plan to look into (hopefully tomorrow).

It might be my lack of understanding all the potential options and combinations here, but it's still weird behavior for me that not setting md-require-match makes it choose a more or less "random" auto complete option when I hit ENTER, while TAB always works. But this is at least fixing the very worst bug for me, the rest seems more like cleanup and refactoring to get more consistency.
