Deleting one preview clears files from the input the widget is living in

[Mikshul]

Prerequisites

• I have searched for similar issues in both open and closed tickets and cannot find a duplicate.
• The issue still exists against the latest master branch of bootstrap-fileinput.
• This is not an usage question. I confirm having read the plugin documentation and demos.
• This is not a general programming / coding question. (Those should be directed to the webtips Q & A forum).
• I have attempted to find the simplest possible steps to reproduce the issue.
• I have included a failing test as a pull request (Optional).

Steps to reproduce the issue

1. Add any number of pictures inside the input
2. Delete any one of them
3. Call $('#input-id-here')[0].files and see the empty FileList

Expected behavior and actual behavior

When I follow those steps, I see the empty FileList, all the items left are still visible inside the preview panel.

I was expecting to be able to continue to crop (I am using Jcrop) and manipulate the items, but because the FileList of the input is emptied, I cannot do that anymore.

On a side note, calling $('#input-id-here').fileinput('getFileStack') returns the list with the items left in the preview.
