Easyadminbundle: Search action - No sortDirection check

[Benjamin-Adrea]

Hello

Describe the bug
In the search action, there is no verification about the value of sortDirection

To Reproduce
Go to the ?action=search for an entity, then update in the URL the value of sortDirection : SQL error

For exemple on the list action, there is a check about that :

http://127.0.0.1:8000/admin/?entity=Image&action=list&menuIndex=3&submenuIndex=-1&sortField=id&sortDirection=ZOBBY

But on the search action :

http://127.0.0.1:8000/admin/?action=search&entity=Image&sortField=id&sortDirection=ZOBBY&menuIndex=3&submenuIndex=-1&query=logo

Fixed by #2343.

@Benjamin-Porquet I love the argument that you used "ZOBBY" 😺
