Remove unused expected_hash variable.

Browse Source 
We stopped setting this nearly five years ago, as part
of bd9cccffce

The big conditional that I removed here should have
always evaluated to false, as I understand the code.
Presumably either the browsers handle # -> '' redirects
better now, or we address this somewhere else in our
codebase.
