Retrieve main user + associated context when getting the default respond via message app.

This CL updates PhoneInterfaceManager#getDefaultRespondViaMessageApplication in order ensure the main user and associated context are used when performing this operation. This is a neccessary change to support HSUM in Telecom since the main user in HSUM mode (user 10) is separate from the system user in HSUM mode (user 0).
