Bug 25041: Restore #ASKED anchor in suggestions table

On commit 4494e8ba6ca7d28972fcc1161c680ecf0b091f62
   Bug 23594: Batch modification for itemtypes on suggestions page
The anchors of the tabs on suggestion.pl has been replaced with
tab_$count instead of the status code.
There was a need at the time, but I cannot remember it.
I restored the previous behavior, and did not find any regressions.

Test plan:
1 - Add several suggestions to Koha
2 - Set them in different status, leaving at least one pending
3 - Go to home page, note it shows count of pending
4 - Click the link on home page
5 - It takes you to correct tab
