Don't fail on missing path attribute

[4levels]

When files are passed in as Buffers, there's no path attribute and this throws.

What does it do?

Allow Buffer argument to the enhanceFile method by testing if the passed file object has a path attribute.

Why is it needed?

Without this, the Upload service fails at the enhanceFile function, making it impossible to handle Buffers. Adding this allows both Buffers & Files to be accepted and handled properly.

How to test it?

Use the service and pass it a Buffer instead of a File, eg a request promise with remote image from a URL
