Wrong return type for getAttributeText($attributeCode)

[diazwatson]

When I pass the a multi-select attribute code to getAttributeText($attributeCode) I get an array instead of an string.

magento2/app/code/Magento/Catalog/Model/Product.php

Line 1717 in 4d26093

public function getAttributeText($attributeCode)

Actually I don't see anything wrong with it but the return tag should be updated accordingly.

Preconditions

1. Magento CE 2.1.9 /2.2 with sample data.

Steps to reproduce

I guess the easiest way to reproduce it is by:

1. Creating a multi-select attribute for a product and add few values.
2. Add the attribute you just created to the attribute set Default
3. Edit a product using that attribute set and select all attribute values.
4. Then you could use (for example)

magento/module-catalog/view/frontend/templates/product/view/form.phtml

to output the attribute values:

print_r($product->getAttributeText('your-attribute-code-here'))

Expected result

I would expect the return to be a string type as the return type says.

Actual result

But the result is instead an array of attribute values.
