a crutch for converting tests, though really, it's enough shorter that it probably should live on.
getPage should be deprecated and replaced with getPage2 which should then be renamed. Joy.
Anyway, WebGUI::Test::Mechanize had a bit of chicken-and-egg going on with not being able to
modify things in its session until after a request with a valid session cookie was made.
It's now more forgiving.
Reworked t/Asset/AssetExportHtml.t slightly to use getPage2 as it currently stands.
