Fix ENS resolution of .eth URLs with query strings

[Gudahtt]

Our ENS resolver for the browser address bar was incorrectly resolving addresses that included query strings. We were concatenating the path property with the search property, despite the fact that the path property already contains search. As a result, search was duplicated in the resolved addresses.

For example, if an IPFS content ID was found for this address, the resolved address for metamask.eth/?foo=bar would have the path /?foo=bar?foo=bar

The original intent was likely to use pathname in place of path. The resolver has been updated to use pathname, and the query string now appears only once in the resolved address.
