test: fix common.mustNotCall error message

[aduh95]

When using util.inspect as a callback, the array index (second
argument) is picked up as the showHidden param, and the argument
array (third argument) as the depth param. This fails with a seemingly
unrelated error message when the argument array contains a
Symbol-related property.

Before this change, the following error was output:

node:internal/util/inspect:1014
  if (recurseTimes > ctx.depth && ctx.depth !== null) {
                   ^

TypeError: Cannot convert a Symbol value to a string

With this change:

node:assert:170
  throw err;
  ^
