Issue Type: Bug

Not sure when another one is added, but there is only one in tasks.json:

This is happening because you keep changing the task. Each time the task is run, we save it as a different recently used task. It isn't ideal, but we can't tell that the task is the same as the one you've already run (because it actually isn't the same, you've changed its core properties).

Couldn't you remove those that are no longer in the task.json?

[alexr00]

Since tasks in the recently used list could also come from extensions (ex. npm, typescript, etc.) I don't immediately know if a recent task came from tasks.json or from an extension. I could annotate tasks that came from the tasks.json and remove those I suppose.
