Enhancement of tests to cover levelized_cost

[OFR-IIASA]

Currently it is not possible to retrieve the parameters calculated endogenously to the core GAMS formulation as part of the solving workflow. These are saved in the GDX output file but cannot be retrieved from the MESSAGEix.Scenario object.

Tests should be added for the levelized_cost calculation, once the parameter can be retrieved.

Retrieving such parameters requires modification of the java-code.

A list of such parameters:
