Steps to reproduce :
- Add a personal dashboard tab named Other (or whatever past "dashboard" in alphabetical order)
- Add the "search in projects" administration delegation widget
- Do e.g. a full search with a blank query, that should return > 10 results.
- Click "next".
=> the "Dashboard" tab is loaded and you don't get the "next results" you wanted.

Hint : the URL generated on "previous/next" button lacks the dashboard ID : as a consequence, when following the link, the default (= first in alphabetical order) dashboard is loaded.
When you manually add the `&dashboard_id=...` parameter in the URL, the behavior is as expected : correct dashboard tab with the widget content updated at the right offset.
