Bug 21931: Do not reset the ES mapping on 3.23.00.050

Bug 21931: Do not reset the ES mapping on 3.23.00.050

This update DB entry uses DBIx schema which does not make it crashes if
the table structure is changed.
Which happens on 18.06.00.054, that added search_field.weight

The entry 3.23.00.050 fails with
  Unknown column 'me.weight' in 'field list'

This patch removes the reset of the mapping and display a warning to
tell the administrator the mapping must be reset/inserted

Test plan:
Use a 3.22 dump and upgrade it
