UserRestrictionsBasicTest::testUserRestrictionsRecordExists() compares an object with a Boolean value

Problem/Motivation

UserRestrictionsBasicTest::testUserRestrictionsRecordExists() contains the following lines.

$restriction = $this->storage->load($this->id);
$this->assertTrue($restriction, 'User restriction exists in the database');

That assertion compares an object with a Boolean value, and it causes the test to fail with an error similar to the following one.

Proposed resolution

• Replace $this->assertTrue($restriction, 'User restriction exists in the database'); with $this->assertNotNull($restriction, 'The user restriction exists in the database');
