Title: test(collapse): add test for ngModel initial value equal to default value

When the ngModel value is zero and we are using the default options (meaning, disallowToggle is false), the binding value will make the first panel toogle because it is equal to the default value. This means the ngModel will be set to -1.

Don't know how to solve this one, just came up when I was checking another thing.
