[autofill] Add missing test.

To avoid regressions, adds a test to validate that when forms are
encountered, the type predictions are appropriately queue to be
sent to the renderer.

Note that this new test validates that the AutofillDriver's
SendAutofillTypePredictionsToRender is called appropriately by
the AutofillManager. It does not tests for the AutofillDriver's
imkplementation of the method.
