[BUGFIX] Proper reference index updating on workspace publish

Yet another reference index bugfix: On workspace publish,
reference index is not properly triggered as already noted
in some of the .csv test files.
The patch moves some of the recently added methods from
DataHandler to ReferenceIndexUpdater and handles cases like
publish correctly.
