[cwvreg] cleanup the event manager when reloading modules Closes #3848995 The event manager callbacks are not cleaned during reloading. So the callback defined in the reloaded module appears twice (old and new version). This may cause problem when the old version is called.

[test] Add missing attribute 'add' permission in test schema Silences yams warning.

[facet html] Add surrounding div with "facetBody" class to "has_text" facet. This makes its html structure consistent with the other facets and fixes both css and a javascript behaviour (hide the facet body when clicking on its title). Closes #3797501.
