Pre-requisites

• I have double-checked my configuration
• I have tested with the :latest image tag (i.e. quay.io/argoproj/workflow-controller:latest) and can confirm the issue still exists on :latest. If not, I have explained why, in detail, in my description below.
• I have searched existing issues and could not find a match for this bug
• I'd like to contribute the fix myself (see contributing guide)

What happened? What did you expect to happen?

The mutex name is not resolved correctly when it is based on a workflow parameter, which is also based on another workflow parameter.

See the workflow below.

1. mutex name is defined as {{ workflow.parameters.derived-mutex-name }}
2. derived-mutex-name is defined as "{{ workflow.parameters.base-mutex-name }}"
3. base-mutex-name is defined as a parameter of the argo submit command line, let's say mycustommutex

In this workflow dag is used (and might be the reason of the defect).

With this workflow, if I run the following command:

argo submit my-workflow.yml --parameter base-mutex-name=mycustommutex

I get the following message indicating the name of the mutex at runtime:

Waiting for argo-wf/Mutex{{ workflow.parameters.base-mutex-name }} lock. Lock status: 0/1

However the command echo {{ workflow.parameters.derived-mutex-name }} outputs correctly the resolved name:

mycustommutex

I have not tested this scenario with the latest version, because I'm not responsible of the deployment of argo in my company.
