Workaround apparent bug in Edge's history.pushState

Browse source 
When attempting to clear the hash state via history.pushState(),
MS Edge in Windows 10 build 10159 errors out with the helpful
"Unspecified Error".

Catching the exception and trying again with a "#" works around
the error and doesn't look any worse than the non-pushState code
path -- and should have no side effects when the bug is fixed.
