Issue with Undo/Redo after Plate solving

After a single image has been loaded and successfully plate solved:

• an undo action will revert the PS (Undo: Plate Solve appears in the console).
• If you want to do a new PS, the RA and DEC data has been erased and can't even be retrieved with the Get MetaData from image button.
• And now after a Redo action, the data re-appear good in the PS window.

This behaviour is from 1.2.0-beta1, not seen on 1.0.6
