$ciphers throws exceptions on newly created objects

Bug Report

Q	A
PHP version	7.3.16
Package version	2.0.0
Framework	Laravel
Framework version	7.9.2

Actual Behaviour

When creating a new object with unspecified attributes (i.e. the column defaults to empty in the database migration) an exception is thrown if one of those unspecified attributes is in the $ciphers array:

Invalid property: "login_ip" {"userId":1,"exception":"[object] (Altek\\Accountant\\Exceptions\\AccountantException(code: 0): Invalid property: \"login_ip\" at /Users/mike/Sites/app/vendor/altek/accountant/src/Recordable.php:146)
[stacktrace]
#0 /Users/mike/Sites/app/vendor/altek/accountant/src/Drivers/Database.php(40): App\\User->collect('created')
#1 /Users/mike/Sites/app/vendor/altek/accountant/src/Accountant.php(81): Altek\\Accountant\\Drivers\\Database->record(Object(App\\User), 'created', NULL, Array)
#2 /Users/mike/Sites/app/vendor/laravel/framework/src/Illuminate/Support/Facades/Facade.php(261): Altek\\Accountant\\Accountant->record(Object(App\\User), 'created')
#3 /Users/mike/Sites/app/vendor/altek/accountant/src/RecordableObserver.php(54): Illuminate\\Support\\Facades\\Facade::__callStatic('record', Array)
#4 [internal function]: Altek\\Accountant\\RecordableObserver->created(Object(App\\User))

Steps to Reproduce

Assuming a typical Laravel User model, but:

Migration:

$table->binary("login_ip")->nullable();

Model:

$ciphers = ["login_ip" => Base64::class];

Controller:

# breaks
$u = User::create(['email'=>'foo@example.com', 'name'=>'Foo Bar']);
$u->save();

# works
$u = User::create(['email'=>'foo@example.com', 'name'=>'Foo Bar', 'login_ip'=>null]);
$u->save();

Possible Solutions

A call to $this->refresh() before $properties = $this->getAttributes() seems to do the trick. (Of course it should only be done on create events, if it's the answer.)
