fix ping, fix send frame close (#49)

Browse Source 
* fix ping, fix send frame close

* fixes for data race on _closeCode etc. and fix test

* fixing one TC

* fix waiting forever if no time to change of readyState, and poll never end

* add 1005 code if no status code received

* fixes for 1005 code

* fix test issue

* fix macOS issue

* revert to master tests and renaming
