fir for #2338

When I go to serials/claims.pl, "All Suppliers (2)" is selected in the supplier
dropdown list, and no missing issues are listed. When I choose another supplier
from that list ("Supplier 1 (2)"), then two missing issues are listed. Should
"All Suppliers" instead read "Choose a Supplier" ?

chris: I think it might be safe to remove the all suppliers option all together as its
doing nothing

paul: agreed, this patch removes the All Supplier line, that is useless, confusing & untranslatable
