[App Management] Fix routing from notification view to permission view.

This CL set the dwellTime in iron-location manually to prevent extra url to be
pushed in window.history stack. This is caused by when navigating from
notification page to detail page, queryParam and path both update, but
they do not happen simultaneously, and this causes observers in
iron-location API get triggered twice, resulting two urls pushed in
history.stack.
