This PR fixing bug described in this issue:
#13768

Problem.

After redirection admin user to user account page (when user password expires), on page pops-up message with text “Something went wrong”.

Reason.

When user password expires, user object has an access only for 3 routes: 'adminhtml_system_account_index',
'adminhtml_system_account_save' and 'adminhtml_auth_logout'.

Any other request (request which lead to other route) will be redirected to “adminhtml/system_account/”. When system loads admin account page (after force password change redirection), fires ajax request (ui form component logic) which leads to route 'mui_index_render' and it redirects to “adminhtml/system_account/”. As result we get those error message and pop-up.

Fix.

Modify “Magento\User\Observer\Backend\ForceAdminPasswordChangeObserver::execute” method by adding to $actionList array 'mui_index_render' route.
