Move blogpost operation doesn't move attachment

The problem:

The move operation ("Tools > Move") moves the blogpost to the new space, but doesn't move the attachment causing the message "Attachment File Not Found" when trying to download the attachment.

Steps to reproduce:

1. Create a new blogpost;
2. Add an attachment to this blogpost;
3. Move the blogpost to a different space.

Additional information:

Enabling DEBUG for the classes persistence.dao.filesystem.UpdateAttachmentsOnFilesystemOnPageMoveListener and com.atlassian.confluence.pages.persistence.dao in the log4j.properties file brings the following information:

• Moving a Page triggers the UpdateAttachmentsOnFilesystemOnPageMoveListener event and the attachments is moved as expected in the filesystem:
