_check_implementations_exist deos not look for implementations in imports

In the method _check_implementations_exist, each implementation is only looked for in self.models and self.programs, and not in self.imports.

Therefore, given a minimal example like:
ymmsl_test_small.zip

running _check_implementations_exist on a.ymmsl raises the error:
RuntimeError: The configuration is internally inconsistent. The following problems were found:
- Component "print" has implementation "print", but no program or model with that name was given. Did you forget to import it?

Even though a.ymmsl contains
imports:
- from b import implementation print

However, the muscle manager can run the example as expected.

Similar issue with custom implementation

Hi Kristoffer,

The consistency check was designed to be run after imports are resolved, in other words it checks consistency of the complete model, rather than of a single yMMSL file. Import statements get removed from the model as they are resolved, so at that point there aren't any to check.

Maybe you can explain what you are trying to accomplish, and we can figure out if something needs to be added to ymmsl-python to support that?
