Stop using the "undef" keyword to remove a constant
The keyword tries to remove a method of the same name which is unlikely to be the intention of this test:
$ ruby -e 'undef Object' -e:1:in '<main>': undefined method 'Object' for class 'Object' (NameError)
Found looking at GH-11497. The NameError triggers error_highlight, which loads a bunch of file under GC.stress set by this test when using Prism. That takes a long time, causing a timeout.
