`beautifyComplexMessage` assumes array elements are strings

[mhofman]

The logic to pretty print EIP-712 messages assumes that nested array elements are strings, and attempts to call toUnicodeBold on them, resulting in an exception being raised back to the caller.

Lines 26 to 32 in 2508d55

	data.message[key].forEach((item: any, index: number) => {
	result += ` ${index}: \n`;
	for (const subKey in item) {
	if (Array.isArray(item[subKey])) {
	result += ` ${subKey}: \n`;
	item[subKey].forEach((item: any, index: number) => {
	result += ` ${index}: ${toUnicodeBold(item)}\n`;
