Subject: [PATCH] Fix queries tag for browsers matches intent filters
 incorrectly

The queries tag in the manifest that declares intent's visibility
with the uri data without the host name should only match browsers'
intent filters. This CL fixes intent filters with a wildcard prefix
in the host name are matched incorrectly by the queries of browsers.
