Initial uncommitted records do not get validated

[saba-mo]

While working on a client app that uses store validation, it appeared that if records were already uncommitted (calling gridModel.store.addRecords() right after calling gridModel.loadData()), then they were not getting validated. Adding await wait() before adding records seems to fix the timing issue with when the StoreValidator is created.

The StoreValidator has a reaction that tracks uncommittedRecords, and we should look into firing immediately.

Reproduced in toolbox - see branch validateUncommittedRecords: https://github.com/xh/toolbox/tree/validateUncommittedRecords

Screenshots from Toolbox branch.

The first screenshot shows the initial row not appearing invalid. The second screenshot is after clicking the Add button, which then validates both records and shows the appropriate invalid display.
