Router: Fix navigating to hash links

[ndelangen]

Issue: #16918

What I did

• fix the handling of the hash-urls which are apparently not supported by react-router

How to test

• go to a component with many stories
• go to docs mode
• click on the bottom story
• expect a hash to be in the manager's URL
• refresh the manager page
• expect the preview to scroll to the bottom

I think this replaces this PR:
#17080

@ndelangen I'm wondering what kind of test we can add so this broken behavior won't raise it's head in the future.

[ndelangen]

@sag1v fair question, I don't have a good idea right now.

Hash/anchor links still do not seem to work (version 6.4.18).

What are you experiencing? Does it load a blank page or just doesn't do anything...?

[VilleMiekkoja]

It loads the component into a new window without the storybook container. It's the iframe.html page version of the component that opens up.

Are you able to reproduce it with a clean minimal project?
