With USE="-doc test", if we have dev-ada/e3-testsuite installed but not
dev-python/sphinx, we end up failing because we don't return early if
*ONLY* USE=test and end up looking for doc deps.
Feel like I'm missing a more elegant way of doing this (other than relying
on just the implicit return which doesnt't simplify much) but let's get
it fixed in any case.
