The 'stack' variable could be #f when code is interpreted, which in
practice happens when running in "legacy" mode--i.e., when
'open-inferior' invokes "guile" instead of "guix repl".
* guix/repl.scm (send-repl-response)[handle-exception]: Check whether
STACK is true before passing it to 'stack->frames'.
* tests/inferior.scm ("&inferior-exception, legacy mode"): New test.
