Revert "Get ContentAutofillDriverFactory::DidFinishNavigation early return back."

This reverts commit e957c5e67218403ebfee98dffcc7e568e479b8d7.

Reason for revert: The CL was landed for temp experimentation, the hypothesis of the "Autofill.Funnel.ParsedAsType.*" metrics drop reason was proofed and the CL can be reverted

Original change's description:
> Get ContentAutofillDriverFactory::DidFinishNavigation early return back.
>
> crrev.com/c/4896011 removed an early return
> `ContentAutofillDriverFactory::DidFinishNavigation`.
>
> We believe that this was the root cause of a change in our metrics.
> The purpose of this CL is to temporarily bring the lines back to
> verify the hypothesis. Once verified, the temporary lines will be
> removed again.
>
> We believe that `driver->Reset()` at the end of
> `ContentAutofillDriverFactory::DidFinishNavigation` led to resetting
> the metric instance variable and that this caused to a change in the
> number of submitted samples, which affected metrics of not-submitted
> Address and Credit Card forms.
