media copied to incorrect sub-directory on clone

[3wf]

Thanks for the great plugin!

Currently I'm having a problem where image attachments often don't come across with a duplication.

I think it's because the file is being copied over from the source but in mpd_copy_file_to_destination() it's using WP functions to create the destination meta data around the attachment which is different if the copy is made when the attachment month has updated.

For example, copying a custom post has the following attachment
./sites/7/2018/04/winemaker_quote_img_vines02_fs_2x-150x150.jpg

And it copies the file to
./sites/6/2018/04/winemaker_quote_img_vines02_fs_2x-150x150.jpg

But the WP media library is looking for
./sites/6/2018/07/winemaker_quote_img_vines02_fs_2x-150x150.jpg

Because WP is now putting attachments into 2018/07
