🐛 Fix clipboard getType error when no allowed types found (#8609)

When clipboard items have types that don't match the allowed types
list, the filtering results in an empty array. Calling getType with
undefined throws a NotFoundError. This change adds a check for null/undefined
types and filters them from the result.
