modules/*: update all taps in context_create()

Mechanical change of ensuring what little taps are implemented
always get updated @ til_module_t.context_create() time as well
as on every frame.

This ensures the pipes are registered on stream immediately upon
context creation, rather than appearing only once the context
gets rendered the first time.
