Variable substitution fails when there is spaces after/before the brackets

[pcastellazzi]

• VSCode Version: 1.13.0
• OS Version: macOS 10.12.5
• REST Client Version: 0.14.4

Steps to Reproduce:

1. Create a file named test.http

2. Add some variables with this snippet to your settings

"rest-client.environmentVariables": {
        "default": {
            "app_server": "https://www.google.com",
            "app_token": "12345678"
        }
    }
}

3. Select the environment we just created with Cmd+Option+E => default

4. Write GET {{ app_server }}/#q=hello+world.

5. Run the query with Send request

I expected to get the result pane with a 200 ok HTTP response and the content. Instead i got this error message: Invalid URI "%7B%7B%20app_server%20%7D%7D/#q=hello+world"

@pcastellazzi nice catch, I have implemented this in version 0.14.5, and you can try it now 😄
