Selected attachment from GalleryGridView will be destroyed when same
attachment is already existed in DraftMessageData. It will make assert
fail during onSaveInstanceState() because mDestroyed in MessagePartData
is true already.
It destroys existing attachment and replaces with new attachment instead
so that selected attachments could be maintained correctly.
Test: 1) Select one image in GalleryMediaChooser.
2) Reopen the chooser and long-press same image again to enter to
the multi-selection mode.
3) Long-press the attachment on draft message to open
AttachmentChooser.
4) Check Assert fail.
