exclude contract test from general rspec test run; refs DE-201

general rspec tests were running contract tests as well as the
contract tests build. contracts-generate-api.sh was duplicating
tests run in rspec.groovy.

test plan:
  - build passes
  - contract tests build runs contract tests as expected
  - rspec build does NOT run contract tests
