Send frame as request paramater as well

Browse source 
Here's what happens: When a client sends simple command without any
values in XML, registry can drop the `raw_frame` parameter
completely. If so, it relies on `frame` parameter being passed on to
create XML document.

https://github.com/internetee/registry/blame/ad823391b75509d5be20ee6ef217aa4f35a4c994/lib/epp_constraint.rb#L14

Fix involves sending the XML string twice, as `frame` and
`raw_frame`, the same as `mod_epp` did.
