[spell] Always prompt user when enabling online spellchecker.

When the user enables "Use a web service to help resolve spelling errors"
option on the settings page, Chrome should confirm the user choice every
time. The patch accomplishes this by passing an undefined "confirmed_pref"
to ConfirmDialog constructor. From the documentation of this dialog:

confirmed_pref: A pref used to remember whether the user has confirmed the
    dialog before. This ensures that the user is presented with the dialog
    only once. If left |undefined| or |null|, the dialog will pop up every
    time the user attempts to set |pref| to |true|.
