Subject: QSqlTableModel: use selectRow() for field and row edit strategies

Calling select refreshes the query data but disrupts view
navigation.

For OnFieldChange and OnRecordChange it makes sense to only
select the row in question. This does not disturb view navigation.

Assume disruption of view navigation is not a problem
for OnManualSubmit because the user or application decides
when submitAll is called.

Task-number: QTBUG-2875
