Previously we did not null out "attributes" in `Span& Span::operator=(Span&& o);`, but we destroyed the arena owning memory referenced by "attributes". Fix that by nulling out "attributes", and rewrite it in a way that's (hopefully) less error-prone.

Previously we did not null out "attributes" in `Span& Span::operator=(Span&& o);`, but we destroyed the arena owning memory referenced by "attributes". Fix that by nulling out "attributes", and rewrite it in a way that's (hopefully) less error-prone.
