fix: Always show an active drag state during the drag (react-dropzone…

…#467)

Currently isDragActive is true only if all files are going to be accepted.
This has several implications:

1. The active state should be applyed based on user interaction independently from validation

Closes react-dropzone#440
Fixes react-dropzone#461

BREAKING CHANGE: isDragAccept acts like isDragActive before. isDragActive is true during the drag.
