AttachmentList option "includePDF" removes other attachments from AttachmentList.dataTypeIds.

### Description of the bug

When using AttachmentList-component the option "includePDF", doesnt seem to work as expected.
If the value "true" is added to the option "includePDF" it will ignore any other attachments from the AttachmentList.dataTypeIds.

Example: AttachmentList with dataTypeIds "datatype1, datatype2", will show a list of attachments with one attachment beeing datatype1 and one attachment is datatype2. If you add the option "includePDF: true" add "ref-data-as-pdf" to the dataTypeIds list, then it will ignore datatype1 and datatype2 from the attachmentlist view.

### Steps To Reproduce

1. Have your applicationmetadata.json include the standard "ref-data-as-pdf" with "enablePdfCreation": true.
2. Add a component AttachmentList to a JSON Layout in ui/layouts
3. Add an attachment ID to the AttachmentList (another then "ref-data-as-pdf").
4. Add "ref-data-as-pdf" ID to the AttachmentList.
5. Check result view and see that only the attachment that is not "ref-data-as-pdf" is shown in the list.
6. Add the option includePDF:true to the AttachmentList.
7. Check result view and see that only the attachment that is "ref-data-as-pdf" is shown in the list.

From my view you can not get both the attachment and the generated PDF to show up in the same list.

### Additional Information

_No response_

Start by locating the AttachmentList component and the handling for the includePDF option. Reproduce the issue with dataTypeIds containing both ref-data-as-pdf and another attachment type, using the applicationmetadata.json and JSON Layout setup described. Done means both the generated PDF and the other configured attachments appear in AttachmentList.dataTypeIds.
