Normalize pasted Zendesk subdomain URLs

Pasting a full Zendesk URL with a path or query (e.g.
acme.zendesk.com/agent?x=1) left the trailing segments in place because
the .zendesk.com suffix no longer matched at the end, producing an
invalid site value rejected by the backend. Drop everything from the
first path/query/fragment separator before stripping the suffix.
