Fix bug when location hash contains a # (#4947)

Browse Source 
The bug fixed in this commit had an interesting side effect when the
location hash started with #, e.g. it looked like wiki.html##foo.
In that case, TiddlyWiki's navigation processing is not triggered and
the browser's navigation processing is used instead, which allows
anchors to be used within tiddlers for sub-tiddler navigation. To
preserve this unintended but useful side-effect, we check for a location
hash that starts with # and ignore it if it does.
