QComboBox: inform accessibility about model change before selecting

QComboBox implicitly selects the first item that gets inserted into the
model. This happens in response to the model's rowInserted signal, at
which point the item view might not have handled the rowInserted signal
yet. Because of that, the view couldn't update the accessibility bridge,
so informing accessibility about a row being selected that doens't exist
in the bridge's representation of the table yet will result in data
being out of sync, and depending on the bridge implementation trigger
asserts.

Fix this by explicitly updating the accessibility bridge before
implicitly selecting the first row.
