differentiate the "check children" and "just your own" cases.
We could theoretically just overload the above method with an extra
"bool recurse = default", but the rules of name hiding for C++ mean
that making a method virtual will hide other overloaded versions of
the same name. This means that virtual automation_control (PBD::ID
const &) would hide automation_control (Evoral::Parameter const &
id).
So, skip around all that with a different name.
