In 29f02a37f0 we bumped the verion of libsass that we use. One
breaking change introduced by the new version is that if a css variable
is interpolated to the empty string, it is still emited in the compiled
css [1]
This commit fixes that by explicitly omitting null values from the map
before looping over it.
