Fix to launch fdn activity on clicking the fdn preference.

Current code will have the intent action for fdn preference
only if 'KEY_WORLD_PHONE_BOOL' config is false. When this
config is true, there is no action on clicking the fdn
preference.

Fix: Allow the intent action for fdn preference irrespective
of 'KEY_WORLD_PHONE_BOOL' config value.
