Martin Probst e0a8376237 fix(compiler): avoid a ...null spread in extraction (#16547)
This code only runs in ES5 mode in the test suite, so this is difficult to test.
However `updateFromTemplate` is being called with a spread operator, as
`...updateFromTemplate(...)`. The spread operator should fail on `null` values.
This change avoids the problem by always returning a (possibly empty) array.
