Can not upload file twice with same name

[RupaliPatwa]

Hi,
I am using <upload component to upload files.
for example: If I upload file a.txt it gets uploaded but If I try to upload same file again it does not get uploaded. onFileLoad event is not called second time.
How to fix the issue? It should allow uploading same file more than once.

This issue is related to #8. This is because we use native file input under the hood, it should be re-rendered after some file was picked. I will try to figure out how to fix this properly
