Modify the existing link format in the shared partial file con-connector-ad-hoc-snapshots.adoc

from:
xref:{link-{context}-connector}#{context}-incremental-snapshots[Incremental snapshots]

to:
xref:#{context}-incremental-snapshots[Incremental snapshots]

Also, insert a "#" that is missing in the properties table link in sqlserver.adoc (last item in the preceding error report).
