Gitattributes file is not respected when switching between branches

Good day

I faced following issue with gitattributes file (at least eol setting) when was trying to force `lf` mode on windows.

We have 2 branches: master & dev. With master set as HEAD in repository

I've added `.gitattributes` with following content to `dev` branch

```
* text eol=lf
```

Now when you clone this repo on other machine and checkout dev branch, eol setting is not respected. As a workaround you can rm all files except .git folder and do hard reset.

Issue is reproducible on windows & unix versions. Test repo can be found on github https://github.com/betalb/gitattributes-issue

master branch - one file without gitattributes feature-branch - .gitattributes added with eol=lf unix-feature-branch - .gitattributes added with eol=crlf

Thanks, Vitalii
