[Ovmsdev] getting started, make errors from debug options?

It is advised to start with .../OVMS.V3/support/sdkconfig.default.hw31
as your sdkconfig and make adjustments from there.

The error you hit is a bug.  The way the conditional compilation is
handled in ovms_module.cpp is to have a dummy instance of the function
that gets included when the necessary infrastructure configurations
are not included.  That dummy instance was not added when the real
module_tasks_data() function was added.  I can fix that.
