Do not create automation when shifting (insert/remove time)

Browse Source 
This fixes a bug when shift() creates automation for parameters that
can not have any automation (hidden parameters, Mixbus PRE).

The GUI (RTAV) aborts() when it finds an automation lane for
a hidden parameter.

This also cleans up shift() operations in general. Empty automation
lanes should be left alone, no guard-point at zero should be added.
