A dep update (OpenUserJS#1136)

* Please note *aws-sdk*@2.50.0 and *aws-sdk*@2.51.0 are a bit shakier than *aws-sdk*@2.49.0
* Error traps should accommodate for the previously mentioned shakiness. This is not currently the HOST.
* If a S3 connection error is detected it should return a 404. Due to the construction of our multiple callbacks/fallthroughs a 502 BAD GATEWAY can't currently be sent... however a 404 says "...but may be available in the future"
* If a stream passthrough error is detected it should return a 404. Due to the construction of our multiple callbacks/fallthroughs a 502 BAD GATEWAY can't currently be sent... however a 404 says "...but may be available in the future"
