UserProfilePage uses AccountProxy instead of AccountProxyInterface

Problem/Motivation

UserProfilePage uses Drupal\Core\Session\AccountProxy instead of Drupal\Core\Session\AccountProxyInterface and does not allow other implementers of the AccountProxyInterface to be used.

Steps to reproduce

Using the UserProfilePage plugin and a module that implements the AccountProxyInterface such as restrict_by_ip will cause a type error:

TypeError: Argument 6 passed to Drupal\context\Plugin\Condition\UserProfilePage::__construct() must be an instance of Drupal\Core\Session\AccountProxy, instance of
 Drupal\restrict_by_ip\Session\AccountProxy given

Proposed resolution

Use AccountProxyInterface instead of AccountProxy

Remaining tasks

User interface changes

None

API changes

Make the constructor of UserProfilePahge a AccountProxyInterface instead of an AccountProxy.

Data model changes

None
