fix(attachments): Don't use currentSession for fetching attachments

When switching pages in Collectives, `currentSession` might still be the
session from the last page. The readonly view (`MarkdownContentEditor`)
doesn't get a session, so the outdated session is used.

Instead, always pass the session from `AttachmentResolver` to
`setAttachmentList`.
