fix: no longer include untracked files in backup stash

[iiroj]

Since v10.1 having untracked files in the backup stash causes revert to fail, because the stash will not apply with the same files already on disk.

Fixes #826

[iiroj]

This happens because when reverting, we call git reset, which doesn't touch untracked files. It's now safe to simply not have untracked files in the stash, because nothing touches them (unless tasks do something).

@okonet Travis integration is broken, but you can see that it passed here: https://travis-ci.org/github/okonet/lint-staged/builds/670434608

I'm unable to merge because the button is disabled.

[okonet]

Yeah I don’t know why it’s not working anymore

[iiroj]

@okonet I rebased this on master, since the release job seems to be working. It didn't generate a release because all commits are of ci type.

So we merge this one and expect a release? Right?

[iiroj]

@okonet Yeah, that should be what's happening since these are fix types.
