Bug 2358 - Remove tests cnsn to json and add tests nn to json

Tests of codecs are included in codecs yangtools yang-data-codec-gson and yang-data-impl but
we test codec on input data and also with presentation of Rest path.

* remove CnSnJsonChoiceCaseTest test
* add NnJsonChoiceCaseTest to nn/to/json/test/
  * positive and negative tests for choice statement
