Comment:

 Using update_post_meta() instead of add_post_meta() converts the array of
 attachment properties to a string when uploading new image. That results
 in php warnings on the Media Library page.

 The patch slightly optimizes update_post_meta() and ensures it calls
 add_post_meta() when the key doesn't exist.
