base: remove OrganisationModule_viewSearchDialog

It was "dead code", this form was not used in any action.

Fields were not following naming conventions, so search would not even
work.

Because we generate search dialogs based on module listbox, organisation
module already had a working search dialog, so this dialog is not needed
anymore.
