LP1805856: Open records in new tabs

Catalogers have given the feedback that it's very helpful to have
certain records open in a new tab after they perform certain tasks.

This commit opens the relevant records in a new tab in the following
circumstances:
1) Cataloging > Z39.50 > Import > Go to record (previously opened in the
existing tab)
2) Cataloging > Z39.50 > Overlay > Overlay (previously did not open the
overlaid record at all)
3) Cataloging > Record Buckets > Merge (previously opened the lead
record in the existing tab)
