Page reloads on spotlight close

[laulaz]

When you close the "spotlight" feature, the page reloads.
This is not the case with the original library (see demo in https://nextapps-de.github.io/spotlight/), even in the same version (we use 0.6.5 in plone.gallery).

This is due to history handling and the fact that the spotlight does a history.go() call when you close it.

I don't know out to fix this "interaction" with Plone in a clean way. Removing history.go() of course works 😜
