Pass correct params to get_site_by_path

[spacedmonkey]

In get_site_by_path it uses the get_sites function to get the a site object. However, the params that are passed to the function are incorrect. The order param in the case of multiple paths and domains, is correctly incorrect and only works by luck of default ordering being the same.

Fixed in [37930], which missed Trac but is in SVN.
