upper case name headers are sended in lower case

[lebretr]

• VSCode Version: 1.5.3
• OS Version: Linux Mint 18
• REST Client Version: 0.8.3

Steps to Reproduce:

1. create a new rest message with specific headers with upper case
   exemple:

POST http://myserver/ws/myapi/v1 HTTP/1.1
Content-Type:application/json
Accept:application/json
Company-Bu-Code:010
TEST:010

{
  "messasge": "0000010001"
}

1. send the message (ctrl+alt+R)

Problem, the specifics headers are send in lower case:
Company-Bu-Code => company-bu-code
TEST => test
