2.7 deprecation in middleware/stack.rb

[Legogris]

This seems to be broken since 2.7.0:

grape-1.5.0/lib/grape/middleware/stack.rb:87: warning: Using the last argument as keyword parameters is deprecated; maybe ** should be added to the call
grape-1.5.0/lib/grape/middleware/stack.rb:11: warning: The called method `initialize' is defined here

Constructor:

grape/lib/grape/middleware/stack.rb

Line 11 in a28d37a

def initialize(klass, *args, **opts, &block)

Problematic calls (AFAICT):

grape/lib/grape/middleware/stack.rb

Line 75 in a28d37a

middleware = self.class::Middleware.new(*args, &block)

grape/lib/grape/middleware/stack.rb

Line 87 in a28d37a

middleware = self.class::Middleware.new(*args, &block)
