Bug 35276: Remove authentication params from suggestion hash

Bug 35276: Remove authentication params from suggestion hash

These would be forwarded to Koha::Objects->as_list and crash on
unknown column.

Test plan:
Logout from staff.
Enter URL /suggestion/suggestion.pl
Without this patch, it crashes. Now it does not.

Note: The crash may show auth_forwarded_hash but I also saw
koha_login_context passing by. Same issue.
