Update CallComposerTuple publish logic and version

The RCC.07 2.6.1.2.5 spec states that open/closed doesnt really have any usage in an RCS context.

Also RCC.07 Table 9 states that call composer via MMTEL should actually be version 2.0, not 1.0 (1.0 is the old version of call composer that relied on a MSRP session)
