Niels Lohmann 38de588582 Reject array insert(pos, first, last) iterators not pointing into an array ...

The array-range insert() overload checked that pos fits the current
value and that first/last share the same owning value, but never
verified that value is itself an array. Passing iterators from an
object, a primitive, or null handed value-initialized (singular)
std::vector iterators straight to array_t::insert(), which is
undefined behavior. Add the missing is_array() check, mirroring the
equivalent check already present in the object-range insert()
overload.
