The is check on type any will always return true.

By not specifying an `is` method the default is method for types which always returns `true` will be used.
Fixes breaking change in 0.2.14 where parameters no longer were allowed to have default values of `0`, `false`, `''`, `undefined`, or `-1`.

Fixes: angular-ui#1915
