Fix for #15147

Commit 7c56295 fixed issue #14947 by changing initializeStringParameter to use localVarX, but didn't apply the same fix to initializePrimitiveOrTypeWrapperParameter which broke my app. This just applies the same fix consistently.

Lets add a test for this to merge

[codeconsole]

@jdaugherty you should be able to replicate via a simple controller

package data.binding.bug

import grails.converters.JSON

class TestController {

    def show(String id) { // success
        render([success: true] as JSON)
    }

    def submit(long id, long imageId) { // error: Cannot cast object '###' with class 'java.lang.String' to class 'long'.
        render([success: true] as JSON)
    }

    def dq(Long id, Long imageId) {  // error: Cannot cast object '###' with class 'java.lang.String' to class 'long'.
        render([success: true] as JSON)
    }
}

curl "http://localhost:8080/test/submit/123456789.json?imageId=123456789"
