cargo web test -- --logfile causes error

[ColonelThirtyTwo]

Caused in some internal code. Stacktrace:

Code segment reveals that there's a typo; it increments a nonexistent variable j (maybe you meant i?)

    const get_filter = function( args ) {
        for( var i = 0; i < args.length; ++i ) {
            const arg = args[ i ];
            if( arg.startsWith( "--" ) ) {
                if(
                    arg === "--skip" ||
                    arg === "--logfile" ||
                    arg === "--test-threads" ||
                    arg === "--color" ||
                    arg === "--format"
                ) {
                    j++;
                }

                continue;
            }

            return args[ i ];
        }

        return null;
    };

FYI this is the only place that argument parsing seems to happen. I'm guessing these options are skipped for compatibility.
