fix: add a WrapperChunk to allow "Invalidating" a ChunkHolder on submission

[dordsor21]

• fixes issues where edits were not fully undone
• invalidate a ChunkHolder when submitting, via a "wrapper" to allow filters to be "aware"/forced to use a new ChunkHolder when it is submitted
• this also allows us to not submit a ChunkHolder in IQueueExtent#filter if the wrapper does not holder it anymore (i.e. it was forcibly submitted, and no more work was done)

~Yet to test with postProcessing history (ran out of time). Would also like to investigate if there's any performance hit (unlikely but you never know).~

Looks like it works fine + nothing new comes up in profiler

Would also be good if others could test and try to reproduce the issue with history (to see if it's "definitely fixed")
