Riak script uses $* not "$@"

[martinsumner]

When the Riak script attempts to forward its args to the relx_riak script, it uses unquoted $* which will potentially mangle any args with a space and split then into multiple args. "$@" should be used instead - https://stackoverflow.com/questions/4824590/propagate-all-arguments-in-a-bash-shell-script/4824637#4824637

Otherwise there are issues if you create bucket types where there is whitespace within the json.
