Stop if there is no encrypted token

Fix #16729

Argument 1 passed to OC\Security\Crypto::decrypt() must be of the type string, null given

Makes sense.

[kesselb]

Looks unrelated to me.

server/tests/Core/Controller/LostControllerTest.php

Lines 703 to 715 in 08a61f3

	$user = $this->createMock(IUser::class);
	$user->expects($this->any())
	->method('isEnabled')
	->willReturn(false);
	$user->expects($this->never())
	->method('setPassword');
	$this->config->method('getUserValue')
	->with('ValidTokenUser', 'core', 'lostpassword', null)
	->willReturn('encryptedData');
	$this->userManager->method('get')
	->with('DisabledUser')
	->willReturn($this->existingUser);

We should return $user instead of $this->existingUser here. Not sure why this is going to break now 🙈

O lol. So the test was wrong. We just never noticed because we catched \Exception.
Good stuff

[blizzz]

looks good to me
