User::class to getMorphClass()

[dosan]

Hello!

It is correct to use 'getMorphClass' with an alias on the 'user_type' field of the History model, rather than directly specifying the '\App\User' class name.

history/src/HistoryObserver.php

Line 119 in bf2c637

return static::getAuth()->check() ? get_class(static::getAuth()->user()) : null;

I suggest
return static::getAuth()->check() ? static::getAuth()->user()->getMorphClass() : null;

Of course, some changes will be required in other files as well.

Thank you for your attention.
