fix(compiler): a lone SSR spread runs after the element's hydration key (#4251)

The lone-spread early return in both compilers passed the spread argument
straight to ssrElement, so `props()` ran in argument position before
ssrElement allocated the element's key. A spread that creates an owner
(a memo) took the element's id on the server only; the client claims the
key before applying the spread and missed the element. The lone path now
defers a dynamic argument behind a thunk, as the multi-source path does.
