More specific error message for sensi faillure cause by bad user parameters #1315
Description
Describe the current behavior
When given a transformer that is not a phase shifter in entry the sensitivity computation rightfully fails returning the following message : com.powsybl.commons.PowsyblException: Two windings transformer is not a phase shifter
Describe the expected behavior
It would be nice to inform the user that there is a issue in the computation parameters.
Something like : Two windings transformer is not a phase shifter, it cannot be used as a TRANSFORMER_PHASE variable
Describe the motivation
This will be more helpful for users
