[common-assets & Library | new-theme]: Fixes for orcid dropdown in authors and increase timeout for addThis check for warning.

1. addThis.component.ts: [Bug fix] Increased timeout to 4 sec and fix check (sometimes innerText was undefined).
2. searchMyOrcidResults.component.html: [Bug fix] Removed uk-animation-fade from results and added uk-scrollspy.
3. showAuthors.component.ts: [Bug fix] Fixed copy to clipboard - data-clipboard-target was not working because we have multiple clipboards in the same page (reverted code to old way of copying).
4. timeout-interceptor.service.ts: Reverted timeout time for client.
5. utils.css: Added custom css for .orcid-dropdown input (orcid dropdown in authors).
