 Currently, if the `__init__` method has default arguments, they are not
 taken into account by `UniqueRepresentation`'s `__classcall__` method. The
 purpose of this ticket is to implement this.

 Hence, with the patch, one has
 {{{
 sage: class Test(UniqueRepresentation, Parent):
 ....:     def __init__(self, a, b=3):
 ....:         pass
 ....:
 sage: Test(1) is Test(1,3) is Test(1,b=3)
 True
 }}}
