Bug 18802: Fix Circulation.t if finesMode ne 'production'

If finesMode is not set to production, only 1 fine will be created (the renewal
one will not). This is what assumes the tests.
If set to 'production', the tests will fail because the fines will not
be deleted (because of the DBIx::Class) warning.
Now we mock the value before charging.

prove t/db_dependent/Circulation.t
t/db_dependent/Circulation.t .. 16/95 DBIx::Class::Storage::DBI::select_single(): Query returned more than one row.  SQL that returns multiple rows is DEPRECATED for ->find and ->single at t/db_dependent/Circulation.t line 491
t/db_dependent/Circulation.t .. 56/95
    #   Failed test 'Can auto renew, OPACFineNoRenewals=10, patron has 10'
    #   at t/db_dependent/Circulation.t line 670.
    #          got: 'auto_too_much_oweing'
    #     expected: 'auto_renew'
    # Looks like you failed 1 test of 6.

Test plan:
  prove t/db_dependent/Circulation.t
should return green whatever the value of finesMode
