Bug 30127: By default show pending suggestions tab

Pending suggestions are the most important ones in links pointing to suggestions.
This tab should be the default one, like did Bug 7875

Changing order in perl code seems really difficult because it is a
generic code using GetDistinctValues()

Test plan :
1) Create some suggetions, accept some of them
2) In staff interface, click on 'More > Suggestions'
=> You see pending tab selected
3) In left menu, click on 'Suggestions' under 'Late orders'
=> You see pending tab selected
4) In left menu, use a filter, then click on '[clear]'
=> You see pending tab selected
5) Create a suggestion, click on 'cancel'
=> You see pending tab selected
6) Create a suggestion, click on 'Suggestions' in breadcrumbs
=> You see pending tab selected
7) Edit an existing suggestion, click on '<< Back to suggestions'
=> You see pending tab selected
8) Create a suggestion, click on 'Submit your suggestion'
=> You see pending tab selected
