Vadim Zeitlin b4eb5438a4 Add a unit test for wxTextCtrl event generation on creation 
Check that creating a wxTextCtrl doesn't generate any events to verify
that this problem doesn't exist in other ports, after fixing it in
wxGTK in 3e7e7dd24c (Avoid generating wxEVT_TEXT when wxTextCtrl initial
value is not empty, 2020-04-01).
