REPLACE_ALL mode of the DefaultModifiableRepeater should delete repeater entry values and not only those present in viewItemAccessor
For exemple, if a repeater entry have attribute A and attribute B, and we call synchronizeValues in REPLACE_ALL mode with a view containing attributes B and C, attribute A will still be filled.
Adding A to the view empty the value, but we shouldn't have to fill the view with all repeater attributes for REPLACE_ALL mode to work
