[drush php]: makeEntitiesAvailableWithShortClassNames throws exception for known class names

[jurgenhaas]

Describe the bug

When calling drush php in drush 12, and there is an entity called Event, that throws this exception:

PHP Fatal error:  Cannot declare class Event, because the name is already in use in /var/www/html/vendor/drush/drush/src/Commands/core/CliCommands.php(313) : eval()'d code on line 1

To Reproduce

Create an entity called Event and start the drush php console. Or you could installe e.g. the DANSE module, which brings an entity with that name already.

This is expected to happen with other entity class names as well.
