SI-8008 Make q”f(..$xs)” only match trees with Apply node
Previously it also matched other nodes but returned Nil as value of xs.
This behavior was added for sake of consistentcy with q”f[..$ts]”. On
the other hand q”f[..$Nil]” == q”f” but q”f(..$Nil)” == q”f()” not q”f”.
Due to this deconstruction/construction symmetry was broken.
On the other hand applications also have q"f(...$xss)" option which is
infact similar to q"f[..$ts]". Splicing Nil into it also results in q"f".
