Remove unused dev dependencies: php-http/httplug, symfony/http-client

Neither package was imported or used anywhere in source or tests.
symfony/http-client was only implicitly needed to make the auto-discovery
test pass; updated that test to instead verify the expected LogicException
when no PSR-18 client is installed.
