Pre-Run script is run PRIOR to path substitution

[MobileVet]

Describe the bug
Pre-run scripts appear to run prior to path substitutions. As a result, if your path is part of an HMAC that is calculated during a pre-run script, it won't have the correct values.

To Reproduce

• Make a Pre-Run script with a single line

tc.request.setHeader("X-Debug", JSON.stringify(tc.request.url))

• Define an endpoint to be called

            "url": "/api/v1/exams/{examMetadataId}/questions",
            "method": "GET",
            "params": [
                {
                    "name": "examMetadataId",
                    "value": "deadbeef01",
                    "isPath": true
                }
  ]

• Call the endpoint
• Read the sent headers
• Notice that X-Debug = http://localhost:5100/api/v1/exams/{examMetadata}/questions

Expected behavior

• The header has the URL with deadbeef01 substituted for {examMetadata}
• X-Debug = http://localhost:5100/api/v1/exams/deadbeef01/questions
