Bug 12406: adding the column maxsuspensiondays in the tests

The column maxsuspensiondays was added in the datatable but not in the tests, which caused the failure of the tests

test plan: execute prove t/db_dependent/Circulation_Issuingrule.t
The command has to print:
t/db_dependent/Circulation_Issuingrule.t .. ok
All tests successful.
Files=1, Tests=9,  2 wallclock secs ( 0.03 usr  0.01 sys +  1.35 cusr  0.08 csys =  1.47 CPU)
Result: PASS
