tf2_ros::Buffer::canTransform sends many warnings if frame does not exist

When I call the tf2_ros::Buffer::canTransform function with a non-zero duration, I can't disable the warning even though I set the errstr argument.

In this line, tf2::BufferCore::canTransform is called without the errstr argument, and the warning is not disabled:
