The goal of this ticket is to fix 3 minor issues introduced when working on SERVER-53104:

• Do not assume that after an update metadata format task we will always have a common task that updates some chunks. This is only true if the Chunks we got from the Config Server are more recent than the ones we have locally.
• I found another minor bug when we compute the enqueued metadata CollAndChangedChunks: at this point we shouldn't set the flag to false but propagate whatever value we have in task.updateMetadataFormat.
• Finally, when we are patching-up (i.e. adding/removing the timestamp) the results that are going to be sent back to the CatalogCache, we need to first update the Collection Info and then patch-up the ChangedChunks, but we are doing it the other way around.
