Refactor simpleArraySearchRule

[fisker]

• Use simple CallExpression selector.

Since prefer-array-index-of listens two different cases, I don't want to merge listeners manually, so I added a .on method to context. ecf02e2

Feel it can be useful, we can

module.exports = {
	create(context) {
		context.on('CallExpression', node => {
			checkOneCaseWithCallExpression();
		})
		context.on('CallExpression', node => {
			checkAnotherCaseWithCallExpression();
		})
	}
}

instead of

module.exports = {
	create(context) {
		return {
			CallExpression(node) {
				checkOneCaseWithCallExpression();
				checkAnotherCaseWithCallExpression();
			}
		}
	}
}

Can be separate into two listeners, we don't have to put two total different logic in one function

Good idea
