Element ref was specified as a string (file-input) but no owner was set...

Hi,
I trying to use material-ui-upload, but see an errors related to new React version:

Error: Element ref was specified as a string (file-input) but no owner was set. You may have multiple copies of React loaded. (details: https://fb.me/react-refs-must-have-owner).

My env:
React v16.2.0
Meteor v1.6.1
Node.js v9.4.0

Link to docs:

https://reactjs.org/warnings/refs-must-have-owner.html

material-ui-upload/src/Upload/index.js

Line 94 in 283faf3

ref="file-input"
