fix: take the changed enum representation into account for array types (#483)

When deciding between the array notations Some[] and Array<Some>, take
the new way of representing enum return types into account.

A method

  getSticky(): Array<Sticky | keyof typeof Sticky>

now should be represented as

  getSticky(): Sticky[]
