HTTP/2: fixed debug log about indexed headers. Previously, "get indexed header" message was logged when in fact only header name was obtained using an index, and "get indexed header name" was logged when full header representation (name and value) was obtained using an index. Fixed version logs "get indexed name" and "get indexed header" respectively.
