WebSearch: temporary move js script on top

• Addresses problems with legacy bibformat elements that include javascript libraries dependent on JQuery. In order to avoid this problem it is recomended to run inveniomanage bibformat bft2tpl and replace all <script src="..."> tags with {% js '...' %}. Eventually move all javascript code in script blocks to individual files to enable script bundling in assets.

• FIXME remove this commit when all bibformat templates and elements are ported and using {% js ... %}.
