ui: Always print the exception upon load errors.
Fixes <https://bugs.gnu.org/34402>.
Reported by <pkill9@runbox.com>.
Previously 'display-error' could be called with the wrong number of
arguments (e.g., for 'git-error' exceptions), and thus nothing at all
was displayed.
* guix/ui.scm (report-load-error): Check whether ARGS matches the
parameters for 'display-error' and call 'print-exception' otherwise.
