[BEAM-9815] Correct go integration test if clauses.  (#11524)
[BEAM-9815] Correct go integration test if clauses.  (#11524)

String comparisons in the integration test script were not running as expected, meaning dev image pushes were not occuring for dataflow, leading to a separate issue. 

Doesn't fix dataflow,but brings it back to the "No artifacts staged" error, which requires a dataflow change to fix.
