Closes #354

To stop the SQL client.py file from being overwritten during initialization I propose changing the client.py evaluation for not in REST or GraphQL from:

{%if cookiecutter.stream_type not in ('REST', 'GraphQL')%}client.py{%endif%}

to the following:

{%if 'Other' == cookiecutter.stream_type %}client.py{%endif%}

My reasoning is that there are 4 streams types REST, GraphQL, SQL, and Other. REST, GraphQL and SQL all have designated client.py files which leaves only a stream type of Other without a designated client.py file.
