Currently, if we receive an error from the underlying client stream, we continue with trying to receive additional data. This causes a hotloop as we will receive the same error again. This fixes it by returning in the error case and adds a unit test for the proxy logic. Fixes thanos-io#3717 Signed-off-by: Sergiusz Urbaniak <sergiusz.urbaniak@gmail.com>
