Reattach Autofill listener after page is loaded.

Some web sites can remove the autofill listeners during initial loading.
This prevents autofill to work.
Trying to catch the removal require a lot of additional code and is not
reliable. Instead try to reattach after a delay.

On eddiebauer.com, the needed delay is between 200 and 300ms.
Try with 1 second.
