Fix (unreported) hair particle 'Delete Edit' missing children hair
updates in particle editmode

Particles themselves were cleared correctly but this was not tagging
batch cache dirty.

Might move this to a utility function later [since it is used in more
places], but that is for after going over some more reports...
