isAdminSecure never used or missing code

[cdiacon]

This property is never used protected $_isAdminSecure = null;

Steps to reproduce

1. Install Magento from develop branch.
2. File Magento\Store\Model\Store.php line 209
   https://github.com/magento/magento2/blob/develop/app/code/Magento/Store/Model/Store.php#L209
3. It looks like this flag is never used or there is missing code or should be moved to a new file?!?

Thanks.

@cdiacon, thank you for your report.
The issue is already fixed in develop branch
But we will consider to backport the fix to patch releases

@magento-engcom-team I don't think deprecations can be backported actually :)
