LP#1198465 CircCommon fine generator repairs

* The latest fine generator uses ID-based transaction lookup.
  Avoid calling ->to_fieldmapper on IDs.

* Consistent with the previous fine generator code, handle each circ,
  reservation, etc. within its own transaction to avoid any long-running
  transactions.

* cstore expects order_by's to be delineated by object class

* CStoreEditor requires all params that are passed through to cstore to
  be contained within the first parameter to a search_*, etc. calls, so
  wrap the query and order_by clauses in an array.

  Without these changes, the fine generator would generate duplicate
  billings when voided billings were present.
