Repair scripts with new React redraw on recording merge page

AcoustID have been added on recording merge page
as dynamic React redraw. https://tickets.metabrainz.org/browse/MBS-2768

So I patched my scripts to wait for React redraws
finish (all p.loading-message disappear).

- mb. MERGE HELPOR 2 (regressions may appear)
- mb. COLLECTION HIGHLIGHTER

Fixes #517 and #518.
