Re-render of publication create doesn't set publisher

[srogers]

Test by adding something invalid for duration to generate:

Publication save failed: ["Ui duration must be a number in seconds or formatted like hh:mm or hh:mm:ss"]

then get:

ActionView::Template::Error (undefined methodmap' for nil:NilClass):`

65: = select_tag :publisher_name, options_for_select(@publishers), include_blank: 'select a Publisher', class: 'form-control select optional'
