Provide ScriptEngine.FILENAME for @JavaScriptResource

[jtulach]

• Debugging of @JavaScriptResource when ScriptPresenter is used was not easy.
• when the JavaScript code is ScriptEngine.evaluated
  • it doesn't have proper file associated
• this PR fixes that by tunneling URL of the resource to ScriptPresenter
• and using it as ScriptEngine.FILENAME
  • when the URL represents a file on disk
  • it does represent it when running unit tests in Maven environment

[jtulach]

• This is the result of debugging the new ScriptEngineEvalTest in NetBeans 30:

• the name of the file is really yield.js as is the name of the file on disk
  • alas, it is not the source file, but its copy in target resources...
• the stack trace rally contains throws.js:21 as verified by assertStackContains in the test
