Revert "simplify SharedString::operator=(&&)"

This reverts commit 2da1cdd31312a70f205f29bb4dfcbc1771409aa4.

Comment from llunak:
I'm possibly not remembering it exactly. But the point is that if you're going to destroy something, it's faster to destroy it outright rather than move it somewhere and destroy it later. If you google it you'll find posts on how implementing std::move() using std:swap() is generally a pessimisation.
