Allow project picker custom field to accept project name

Currently, project picker custom fields are not available under the field selections in edit fields actions. The workaround to this would be to edit the field via JSON.

However, when editing via JSON, we are only able to use ID or project key. As an example, this works:

{
    "fields": {
        "testprojectpicker": {"key":"TEST"}
                 }
}

But, this does not work:

{
    "fields": {
        "testprojectpicker": {"name":"test"}
                 }
}

In the audit logs, we see the following which suggests it would only accept ID or project key.

We would like to ask for project name to be accepted here.
