allow Grist front-end to function when location history is unavailable (#596)

Browse Source 
* allow Grist front-end to function when location history is unavailable

When the Grist front-end is embedded in an iframe, using a srcdoc
attribute, history.pushState and similar methods are unavailable.
Currently, that makes it impossible to navigate between Grist pages,
since an access error is thrown (behavior may be browser dependent).
With this change, navigation succeeds.

* give unrelated possibly slow test a little more time
