Dependency between `nest.CopyModel` and `nest.Install`

[med-ayssar]

Describe the bug Once the functionnest.CopyModel is called, it prevents from installing further modules, and I don't see any necessary dependencies between copying an existing model and installing a new one.
To Reproduce Steps to reproduce the behavior:

1. Install an existing synapse model synapsemodule.so
2. Call nest.CopyModel("installed_synapse_name, "new_synapse_name")
3. Install an existing neuron model neuronmodule.so
4. After the call in the third step, SLI throws the following:
   • DynamicModuleManagementError in SLI function Install: Modules cannot be installed after CopyModel has been called

Expected behavior nest.CopyModel and nest.Install must be decoupled.

@jougs Do you think this will be fixed with the module system refactoring?

[jougs]

Yes, this restriction should go away then. Possibly already with the merge of #2208, but I lost the overview a bit on that one...

I have tested this again with the current NEST version, and it seems that it has been already fixed!
