Bug 981989 - [DSDS] Fixed dialing numbers page is not separated for 2 SIM card, which means that if set SIM 1 to enabled, same page of SIM 2 will become enabled as well even it's disabled in Call settings.

The FDN status was not refreshed in the FDN settings page, so it always would adopt the status of the last card checked for it. This patch adds a check whenever the FDN Settings panel is ready.
