Pass 'argv' to the server if parsing it on the client side returns 502. This can happen when coderefs in cmdline_aliases in metadata got converted into string 'CODE' due to having to be transported via JSON from the server side (Riap::HTTP/Riap::Simple). This also requires a recent version of Perinci::Access::Perl (0.64) on the server side, which supports accepting 'argv' request key for the 'call' action.
