Title: Fix parsing of minus operations in expressions

Really have no idea what exactly this is doing!? Just tried to get the same behavior as with `+`, since that was already working. Not sure if some one of those `peeks` could be removed now!? Anyhow, this seems to fix https://github.com/sass/libsass/issues/361 and not breaking any other spec tests!
