Common transformer tests (#97)

* Move chop lump transformer test to a generic log_note_transformer_test * Add test cases to transformer test - cat file flip - cat file pit vow - deal - dent * Move transformer tests over to transformer factor test file - drip drip - drip file ilk/repo/vow - pit file deb ceiling/ilk/stability fee - price feeds * Move LogNoteTransformer test into factory package and remove log specific transformer tests * Move Transformer test into factory package and remove log event specific transformer tests * Respond to PR comments
