only update on location changes

[autarc]

Currently a replace action is forced on any store dispatch at the initial route. Aside of polluting the log its also a problem in case history.listenBefore is used asynchronously. It triggers the listeners although the route didn't change.

Can you write up a small test to accompany this? Or do you have a use case I can look at?

[autarc]

Checked if writing a test would be reasonable, but ended with renaming the existing handles toggle after store change into handles toggle after routing store change which seems redundant. The issue is that each time the store gets updated the replace action is triggered even at the initial page, not only when there is an actual change towards routing but whenever an action gets dispatched.

This leads to errors regarding beforeListen((location, callback => ...) which will be triggered multiple times if an action is dispatched to set data for the next page. You can find here an example with asynchronous fetching at the client.

@autarc Have you looked at #268 ? I was having the same issue, it was fixed in new version.

This is going to be superseded by 4.0.0, so I would upgrade to the rc.1 release and see if that works better for you. If not, open an issue on that version and we'll see about getting it fixed.
