BUG: missing push_header method in Response::Delayed

[clemep-sios]

This is a request to fix Response::Delayed to avoid incompatibilities with the base Response type, such as:

[Mon Jan 18 12:11:19 2021] trace: Entering hook core.app.after_request
[Mon Jan 18 12:11:19 2021] error: Exception caught in 'core.app.after_request' filter: Hook error: Can't locate object method "push_header" via package "Dancer2::Core::Response::Delayed" at /root/perl5/lib/perl5/Dancer2/Plugin/JWT.pm line 237.
 at /usr/local/share/perl5/Dancer2/Plugin.pm line 597.
 at /usr/local/share/perl5/Dancer2/Core/Role/Logger.pm line 151

The following simple patch fixes this:

$ diff -pu Delayed.pm{.orig,}

Thanks! I appreciate you finding this and pointing us to a fix!

Any chance I can get this as a PR with a test for the release I am working on?

Hopefully the tests are in an appropriate place.
