Bug 14008: Display active filters when searching for reports

On the saved report list, the filters on the left are not displayed.
It means that some can be set, but the user has not visible feedbacks.

How filters work here:
If a user set a filter, it is saved in the session. Next time he will
come on this search, the previous values will be kept.

This patch just displayed the filter's values in the input fields.

Test plan:
Search for reports by date, author and keyword.
The filters should be displayed after you have clicked on the submit
button ("Apply filter").
