Evangelos Ribeiro Tzaras db7674d0f9 manager: Add new set of add and remove signals for CuiCalls 
This is part of a refactoring which should help separating concerns between
CallsCall and CallsUiCallData better.

To accomplish this we want to stop passing around CallsCall objects and instead
pass CallsUiCallData objects.
In this commit we added new signals instead of changing the existing ones
because that results in a lot of churn. It allows to do the switch per module
allowing smaller individual patches and a more manageable patchset.
