Validate budget period add row after add line dialog fix and
update error messages
Scenario here is that we display the validation message in the dialog when rule fails and when passed, close dialog and insert the period.
Issue here was that on second run, the dialog displayed the initial error message where as rule passéd this time and period was inserted where as dialog did not close since error message exists.
I will remove the clear message and retest.
