Can not jump to bounds on the first view of the top page

[dadiorchen]

Previously, we can jump the the map view that is brought in the URL, like this: https://map.treetracker.org/top?bounds=7.998046875000001,-30.145127183376115,71.27929687500001,29.99300228455108

Now it is broken, we need to fix it and when we open the url above, the map should directly jump the the location expressed by the bounds

After analysis, the problem is: JUST for top page we can not jump the bounds, because we are missing the code for bounds detection.

I will fix it.
