[resolver] Fix nullptr dereference when validating continuing block

ast::IdentifierExpression nodes can appear outside of functions
(e.g. as initializers for module-scope variables), so we cannot assume
that current_block_ is not nullptr.

We already have several tests that do this, but for some reason the
nullptr dereference does not cause problems on our presubmits.
