Overloading Class Example doesn't pick up correct constructor

[lewisfogden]

From testing the second block of code here, but with a more explicit example:

https://docs.exaloop.io/codon/language/classes

class Foo:
    x: int
    y: int

    def __init__(self):                    # constructor
        self.x, self.y = 0, 0
        print('empty', self.x, self.y)

    def __init__(self, x: int, y: int):    # another constructor
        self.x, self.y = x, y
        print('int int', self.x, self.y)

    def __init__(self, x: int, y: float):  # yet another constructor
        self.x, self.y = x, int(y)
        print('int float', self.x, self.y)


Foo()
Foo(1, 2)
Foo(1, 2.3)
a: int = 3
b: int = 5
Foo(a, b)

Output:

> codon run example.py
empty 0 0
int float 1 2       <- should be int int 1 2
int float 1 2
int float 3 5       <- should be int int 3 5

Note that swapping the __init__ order so that the float constructor is first works successfully. (i.e. method definition order matters)
