CocoaHTTPServer 2.3.0 installed via cocoapods compile error

[Oleksiy-Yakovenko]

Repro:

1. Create a new mac application TestProject in objective c
2. Add a Podfile with the following, then run pod install:

def macos_version; '10.14' end
platform :osx, macos_version
use_frameworks!
inhibit_all_warnings!

workspace 'TestProject.xcworkspace'

target 'TestProject' do
  project 'TestProject.xcodeproj'
  pod 'CocoaHTTPServer', '2.3.0'
end

3. Open the generated TestProject.xcworkspace
4. Add #import <CocoaHTTPServer/HTTPServer.h> to any objc file, such as AppDelegate.m
5. Observe it fails to build because of import order or something similar in the generated CocoaHTTPServer-umbrella.h

CocoaHTTPServer 2.2.1 works just fine though.
