Set file path in ApplyCodeActionEdits

EditorServices invokes PSScriptAnalyzer by passing `ScriptDefinition` paramter and not `Path` parameter. This results in null value of `ScriptPath` property of the returned diagnostic record which in turns leads to null value of `edit.file`. Therefore, we need to retrieve file path from the active editor.
