Don't use hidden INVALID_SUBSCRIPTION_ID

Alternatively, I could unhide INVALID_SUBSCRIPTION_ID.
However, the affected code doesn't actually need to know
the value of SubscriptionManager#INVALID_SUBSCRIPTION_ID.

ContactsCommon simply uses INVALID_SUB_ID when the value
for subscription ID doesn't matter, because we know
the mSubscriptionId value won't be read later.
