Fix #30132: "Add Game Property" works incorrect after "Add Text Game Property"

Issues was caused by operator props "presets" which was reusing name of property
on every run of OBJECT_OT_game_property_new. This run into conflict with how text
property is determining -- it's stupid name comparsion which worked unexpectable
after adding and removing text property.

Solved by using empty (default) name for game_property_new when crating game property.
