Make dependency-submission and setup-gradle play nicely

Now, a `dependency-submission` step will trigger a dependency-graph
generation, even if it follows a `setup-gradle` step in the workflow.

Similarly, a `setup-gradle` step with `dependency-graph` configured
will function as expected even if it follows a `setup-gradle` step.
