Commented Issue: Underscores into user images [2637]

Hi,
I think there is some problem when the library returns the path (ProfileImageFullSizeUrl) of a user.
In particular, the error is present when the original url has an underscore.
Seems the library lose the underscore returning a wrong image path.

ie:

Trying to receive the Demi Lovato's image:

var user = Tweetinvi.User.GetUserFromScreenName("ddlovato");
var imageUrl = user.ProfileImageFullSizeUrl;

the variable imageUrl returned is "http://pbs.twimg.com/profile_images/614150024847605760/HrQVHpR.png"
while the current and correct url on Twitter is "https://pbs.twimg.com/profile_images/614150024847605760/HrQVHpR_.png"

Thank you.
Stefano

The problem is still present...

Please, try with the twitter account @googleitalia. In this case the profile image url is "https://pbs.twimg.com/profile_images/638746415901114368/e4h_VW4A_400x400.png" (with 2 underscores) but, invoking your new method "ProfileImageUrl400x400", I obtain the following url:
"http://pbs.twimg.com/profile_images/638746415901114368/e4h400x400.png" (without the underscores).

Best regards
Stefano
