A boolean false breaks querybuilder update

[that-guy-iain]

Bug Report

Q	A
BC Break	no
Version	2.19.5

Summary

When you use false boolean value in the set of the querybuilder it doesn't work as expected.

$queryBuilder = $this->entityRepository->createQueryBuilder('t');
$queryBuilder->update(TaxType::class, 't')->set('t.default', false);
$queryBuilder->getQuery()->execute();

Current behavior

It causes the following error message

Warning: Attempt to read property "type" on null in vendor/doctrine/orm/src/Query/Parser.php line 2928

but it works if you put in 'false'

How to reproduce

Create an entity with a boolean value and then try to set it using the query builder with a boolean false.

Expected behavior

For it to know that false is a boolean value and value for the boolean value or to return an Syntax error instead of trying to access full.
