Fix the issue documented in #1277
Adds checks for non-SPCT transformers to check for connections to triplex devices or having phase S.
Migration of fix from https://github.com/gridlab-d/gridlab-d/issues/1432
Added extra autotest to ensure this errors, though it could still technically pass on the previous failure.
