Not able to do file download validation with run-multiple execution

#### What are you trying to achieve?
Validating the file download using handleDownloads and FileSystem helper, like using methods I.amInPath('output/folderName');
with run-multiple execution with multiple browsers like Chrome, Safari, Firefox and Edge, and check whether file is there in the subfolder in the output folder parallel_output_1, parallel_output_2, parallel_output_3 etc
#### What do you get instead?
Not able to use the dynamic path in the method I.amInPath('output/folderName')
Tried this way I.amInPath('output/parallel_output_*') but not working

首先跟踪 run-multiple 的执行入口，以及报告中提到的 handleDownloads 和 FileSystem 辅助方法。使用多个浏览器和 parallel_output 目录重现该情况；当 file-download 验证接受生成的输出路径，而不是要求固定的文件夹名称时，即表示完成。
