Magento2: setup:config:set --key append instead of replace

[ju5t]

Preconditions

This particular container/server runs PHP 7.0.23 and Magento 2.1.9 which was downloaded from the website.

Steps to reproduce

# bin/magento setup:config:set --key=test
Overwrite the existing configuration for key?[Y/n]Y
You saved the new configuration.

Expected result

To replace the value in crypt => array('key' => '').

Actual result

It appends the value to crypt => array('key' => ''). This will result in:

  'crypt' =>
  array (
    'key' => 'test
test',
  )
