Dselans/protos v0.1.16 updated

[dselans]

Several bits here:

1. detective wasm was missing "return" for err case in validate_wasm_request -- was never hitting it - this made it difficult to write a test for on_error
2. pipeline status wasn't getting filled out in an edge case - if last pipeline and last step AND step is said to abort current pipeline - resp would never get updated status
3. Tested on_error
4. wasm was returning FALSE on validate_wasm_request instead of ERROR
5. died up tests
