MPLY-8765: Utilises default tags, buddy: Michael C

When a mapscene was being parsed `m_tagSearchRepository` and
`m_previousTagSearchRepository` where being cleared and repopulated.

If there were no custom search tags in the mapscene, only
`m_tagSearchRepository` was being populated with defaults. Now both are
being populated with the default search tags.
