`prefer-ternary`: interaction with no-else-return

[geoffswift]

Description

So unicorn/prefer-ternary does not play nicely with the standard rule no-else-return.

With this example

// ❌
function example() {
	if (test) {
		return a;
	} else {
		return b;
	}
}

no-else-return autofixes it like so...

// ❌
function example() {
	if (test) {
		return a;
	} 
	return b;
}

Examples

So ideally unicorn/prefer-ternary would autofix as per this example...

// ❌
function example() {
	if (test) {
		return a;
	} 
	return b;
}

// ✅
function example() {
	return test ? a : b;
}

Additional Info

Maybe having no-else-return isn't that great, but still an opportunity to improve here.
