limitation in unparser makes Component() fail

[janbiedermann]

A limitation in unparser makes usual component calls without arguments fail in all blocks that are send to the client (evaluate_ruby, expect_evaluate_ruby, Mount, etc.), example:

          class Comp
            include Hyperloop::Component::Mixin
            def render
              "whatever"
            end
          end

          class SuperComp
            include Hyperloop::Component::Mixin
            def render
              Comp()
            end
          end

Workaround is simple, pass a silly arg:

          class Comp
            include Hyperloop::Component::Mixin
            param :silly
            def render
              "whatever"
            end
          end

          class SuperComp
            include Hyperloop::Component::Mixin
            def render
              Comp(silly: 'arg')
            end
          end
