Visual swatch images/colors were not visible in backoffice
Description
In
app/code/Magento/Swatches/Block/Adminhtml/Attribute/Edit/Options/Visual.php
at line 95: $newSwatch was initialized as a string but it was used as an array in both the function body and in the calling function.This resulted in $newSwatch was always set to "b" (the first letter of "background"), and so the view did not get a correct value for
style="background: url('xxxxx.xxx'); background-size: cover;"
This issue is only visible for PHP 7
