getSignedAndUploadToS3 is not catching exceptions occurred in getSignedURL

[dariaedicas]

hi. we've noticed that if our endpoint that makes presigned url returns error (500 or 502), vue2Dropzone plugin crashes with exception
vue2Dropzone.js?2af3:185 Uncaught TypeError: Cannot convert undefined or null to object
at Function.keys ()
at Dropzone.eval (vue2Dropzone.js?2af3:185)

steps to reproduce:

1. raise an error in "signingURL" endpoint
2. try to upload a file to AWS S3

actual behavior: unhandled JS exception

expected behavior: event vdropzone-error OR vdropzone-s3-upload-error emitted

thanks
