OAuth failing because oauth_token is not encoded.

[sharok]

Expected Behavior

OAuth authenticator should get access token.

Actual Behavior

Using OAuth1Authenticator.ForAccessToken I get an error from the provider that oauth_token is absent. But it exists in the header.
After debugging the source code, I figured out that RestSharp doesn't encode oauth_token.

After changing the line in OAuthWorkflow file:
if (!Token.IsEmpty()) authParameters.Add(new WebPair("oauth_token", Token));

to

if (!Token.IsEmpty()) authParameters.Add(new WebPair("oauth_token", Token, true));

I was managed to get access token.

PS. I use ETrade exchange broker in this case.

@alexeyzimarev could I have your attention here, please. Because this issue is a big blocker right now.
I can send PR for this, all tests pass, but I cannot check integration tests, because LinkedIn doesn't allow to create OAuth 1 keys anymore, Twitter rejected my application.

@sharok it would be great to get a PR 👍
I have Twitter keys, so I can test it locally. I am unable to put it in the CI since it requires a manual step.
