Stop generating tests by openapi generator (#1667)

The template file that generates code, and the template file that
generates tests basically share the same logic. In short, testing
generated code with the same logic is not meaningful.

We already removed this in ine-bot-sdk-java. It only increases
maintenance cost, so let's remove it here as well.

Manual tests should be sufficient. This change also adds some tests to
keep coverage.
