[GoSDK Infra] Bugfix: Parallelism ignored when using endpoint flag.

The parallelism flag is intended to be ignored when using Flink, Spark, or Samza runners, but due to a bug, this wasn't happening if one of those runners was used with an endpoint address instead of a job server jar. This fixes that.
