HPCC-12053 Make relative filename handling consistent.

Fixes regression introduced by HPCC-12037

Uncovered some inconsistencies in how names in meta info were
published when dealing with relative logical names.
One interestnig difference, exposed that UPDATE on relative
logical names wasn't working, causing in effect the UPDATE to be
ignore.

Could possibly combine this StringBuffer temp, addScope, set() into a single function, since it occurs quite a few times.
