[Core] Fix condition creation in sub model part

[ddiezrod]

📝 Description
I have encountered a problem when trying to create a new condition with a vector of nodes. The current implementation assumes that the nodes belong to the model part, but this is not necessarily the case if it is a submodel part. For some reason, this was fixed for the elements but not for the conditions. I think it makes sense to do the same for both functions (see

Kratos/kratos/sources/model_part.cpp

Line 980 in f6e7a3c

if (IsSubModelPart())

)

Looks Okay, but maybe wait for the approval of someone from @KratosMultiphysics/technical-committee

Just to be clear, the problem arises when we are in line

Kratos/kratos/sources/model_part.cpp

Line 1521 in f6e7a3c

pConditionNodes.push_back(pGetNode(ConditionNodeIds[i]));

and we try to do a pGetNode. If it is a submodelpart, it might not have the node.

Makes very much sense. Thanks for the fix.
