This test was written to assume that the stdout stream would deliver LSP headers and body in separate "packets", but wasn't guaranteed to be the case. The failure at https://dart-ci.appspot.com/log/pkg-linux-release/unittest-asserts-release-linux/19779/pkg/dartdev/test/commands/language_server_test shows that both header+body arrived together which caused the test to fail. These changes buffer the output until the complete message is available and then return the body of the message.
