Serilog: refactor url and server population

[andreycha]

• Fix query string population according to the specification (closes #198)
• Use only HttpRequest to populate url and server fields, without creation of Uri instance
• Put original full URL into url.original instead of just path (according to the spec)
• Put host name into url.domain and server.domain
