Bug 12332: Fix for tab "Purchase suggestions" not lighting up

This patch changes the file purchase-suggestions.pl with "suggestionsview => 1" for the template parameter.
In circ-menu.inc i changed the condition from "suggestions" to "suggestionsview" since it seemed to conflict with the existing variable suggestions (and in that case only highlighting the tab when there were suggestions).

Please note that I fixed the troubles with the tab "Fines" in a separate patch 9245.

Test plan:
1) Verify that "Purchase suggestions" does not light up as it should when clicked.
2) Install the patch.
3) Verify that the tab "Purchase suggestions" now actually light up when clicked.
