Fix radio button bug on sync_page.html

The second radio button in the passphrase section
was not visibly checked on selection.

To solve this, move the spans containing the conditional
strings inside one radio-button, instead off having two
conditional radio buttons.

Additional change:
 - Remove aria-label attribute because the visible text
   is used automatically as radio button title.
