Hitting back lists last used custom report but eprint report fields

[drn05r]

On Chrome and Edge (but not Firefox) if you perform a search using the Users custom report and then click back from the search results and then open the "Custom Reports" tab again it will still display Users in the select form dropdown but will display the fields for the EPrints search form.

This is probably because initReportForm in javascript/auto/reports.js does not run again, if the page is accessed via a "back" click, so some cache that Chrome and Edge browsers has loads the last option selected on the select form dropdown. It is not clear why Firefox does not have the same behaviour.
