Usage Settings: Fix NPE when subscriberId is Null.

Browse Source 
For mobile, a old API: buildTemplateMobileAll doesn't includes the
merged wifi network, call the new API: buildTemplateCarrierMetered
to replace the old one.

But new API: buildTemplateCarrierMetered requires non-null subscriberId.
Call old API: buildTemplateMobileAll when subscriberId is NULL since
the matched result is always empty when subscriberId is NULL. No any different
between buildTemplateCarrierMetered and buildTemplateMobileAll.
