Fixes expressjs/multer#1218. No response in Pending status.

[bettep-dev]

When a file upload is in progress in the native app, a network communication timeout occurs in the Pending state,

but I verified that the busboy.on('close') event does not fall into the Pending state.

I modified the code to handle errors in storage._handleFile.

See: #1218
