URLs do not have to have a path; currently our npm URLs don't, so
encodeurl() needs to handle if the path element isn't specified. This
fixes errors using OpenEmbedded's devtool add / recipetool create on an
npm URL after OE-Core revision ecca596b75cfda2f798a0bdde75f4f774e23a95b
that uses decodeurl() and encodeurl() to change URL parameter values.
