Bug 86122

WebKit's IDB implementation enforces an older spec restriction, namely that during the call to IDBOBjectStore.add/put(), if evaluating the key path of any index yields an invalid key the add/put should - instead, they should be ignored. The spec was updated to drop this restriction (indexes key paths are not checked at all during the add/put call). The steps for storing a record now say: http://dvcs.w3.org/hg/IndexedDB/raw-file/tip/Overview.html#dfn-steps-for-storing-a-record-into-an-object-store 7.2 Evaluate index's key path on value. If this does not yield a value, take no further actions for this index. Otherwise set the result to index key. 7.3 If index's multiEntry flag is false or if index key is not an Array, and if index key is not a valid key, take no further actions for this index. 7.4 If index's multiEntry flag is true, and index key is an Array, remove any elements from index key that are not valid keys and remove any duplicate elements from index key such that only one instance of the duplicate value remains.
