Bug: Assigning null to ?array $identities property without proper handling

[WCrash7]

the $identities property is correctly declared as nullable array:

shield/src/Entities/User.php

Line 50 in d07c0f9

private ?array $identities = null;

However, in several places, we directly assign null like these:

shield/src/Entities/User.php

Line 130 in d07c0f9

public function setIdentities(array $identities): void

shield/src/Entities/User.php

Line 149 in d07c0f9

$this->identities = null;

TypeError: CodeIgniter\Shield\Entities\User::setIdentities(): Argument 1 ($identities) must be of type array, null given,
