Fix additional Ruby 2.7 keyword warnings

[stefansundin]

These were missed in #1581.

If you hope eliminating the warnings, why didn't you fix other points such as "send_file"?

Also, AFAIK, the "opt = {}" with keyword args will be kept as compatibility layer as per https://blog.saeloun.com/2019/10/07/ruby-2-7-keyword-arguments-redesign#compatibility-layer

So I guess we don't have to merge this for v2.7, right?

I got the warnings from sinatra/reloader when loading my app in dev mode. I was curious, so I tried to require all the sintra-contrib files, and the only other one that gave me a warning was sinatra/respond_with.

I don't know why the other methods with options = {} don't trigger the warning, but these three definitely do. As for why I didn't fix send_file, I don't think it requires fixing. Please double check this though.

And like that other PR that is already merged, this isn't strictly required, it just prints an annoying warning when the files are included with require.

@stefansundin Thanks.

@jkowens Could you check in term of other things.
Also I would like you to check the thing I pointed out (e.g. send_file).

@jkowens Could you take a look at this? I think we can merge it. Thanks!

@stefansundin I found two more locations that are throwing warnings when I run the tests. Can you fix those as well? 🙏

sinatra/lib/sinatra/base.rb

Line 1526 in 2527f46

handler.run(self, server_settings) do |server|

sinatra/sinatra-contrib/lib/sinatra/namespace.rb

Line 335 in 2527f46

result = base.send(method, pattern, conditions, &block)

Hi @jkowens. I'm having issues installing libv8 on my machine, so I can't test it unfortunately. Could you tell me exactly what to change those two lines to?

I think you can also propose the exact changes in a review: https://help.github.com/en/github/collaborating-with-issues-and-pull-requests/reviewing-proposed-changes-in-a-pull-request

And since you are a member of the Sinatra org, I think you have write access already to this branch. Feel free to push to it yourself.

Ok, I ended up only updating one other location. The warning at sinatra/base.rb#L1526 seems like it will need to be addressed by the rack handlers (Puma, etc).
