Fix destructure structs implementation

Resolves #2

@danielberkompas please have a look

Shouldn't this be refute d(%People{}) = %Person{}?

[muhifauzan]

No, if we use assignment match, it will raise MatchError before refute evaluation takes action. Try using assert d(%People{}) == %Person{}, we will get the expected failure

1) test structs can't match with different structs (DestructureTest)
     test/destructure_test.exs:17
     Assertion with == failed
     code: d(%People{}) == %Person{}
     lhs:  %DestructureTest.People{people: nil}
     rhs:  %DestructureTest.Person{email: nil, name: nil}
     stacktrace:
       test/destructure_test.exs:18: (test)

Or should I change it to use assert_raise? I guess it's more make sense to do it

Looks good to me, @muhifauzan!
