Reload dialog shown when adding folder with sub folder and calling browser.browse()

The document wizard plugin triggers a bug in the CMS. When you already visited the document browser and try to create a document in a new folder, an error dialog pops up.

Reproduction path GoGreen:

1 - go to https://cms.demo.onehippo.com/
2 - login
3 - go to browse
4 - navigate to the news folder
5 - go to dashboard again
6 - click "create a news document"
7 - fill in "name" and "11/14/xx" where xx is a non-existing folder year (31 for 2031) in the /news folder
8 - click "ok"

Observed: You get a message "There was a problem updating the tree. It might be caused be the old page being cached by the browser. It is recommended to reload the page. Do you want to reload it?".

Expected: You go directly to the freshly created document in edit mode.
