generate-run-command handles --pass-config in a wrong way

[YevheniiSemendiak]

Description:

If you run a job with --pass-config enabled and afterward, use generage-run-command, the resulted command will contain:

• the--pass-config flag, which under the hood uploads config to storage, and mounts it to the job with volume and ENV variable.
• a pass-config-related volume and ENV variable from previous run

As a result, the setup will be conflicting and you will not be able to re-run the job.

Example:

1. `neuro run --pass-config --name test-pass-config ubuntu bash -c "exit 0"
2. eval $(neuro job generate-run-command test-pass-config) - fails.
   Also, the error reported by CLI is not clear:

Expected behavior:

generate-run-command does not mount previous --pass-config volume and ENV.
