URL fragments are currently unsupported

[mikabytes]

Describe the bug
using URL fragments "hash urls", the behavior differs from the use of regular pushState

To Reproduce

1. Create a page that match URL /#/page1 and another /#/page2
2. Add a touchable that navigates to page2 from page1.
3. Go to page1 and click the touchable
4. Click back-button

The URL will change back to /#/page1

Expected behavior
Nothing should happen (this is the case with regular pushState). In Tiden, URLs should not change automatically when browser popstate.
