Problem with strings in a command.

Created by: Kiritsu

Make sure you familiarize yourself with our contributing guidelines.

Summary

We have a command with one unique string parameter, with or without [RemainingText] attribute. Sometimes, the command will never being fired. That happened when I tried to put a YouTube link as a parameter of the command.

Details

.NET Core 2.0, Windows 10 Enterprise 2016 LTSB Using Visual Studio 2017 v15.6.4

DSharpPlus version : v4.0.0-beta-00439

There is no error, nothing threw up. I tried to subscribe to CommandErrored event, it's not being fired when I try the command.

Steps to reproduce

Just use this command:

[Command("Test")]
public async Task Test(CommandContext ctx, string input)
{
    await ctx.RespondAsync("Fired! `" + input + "`");
}

Admitting you have the following prefix: ! Try the commands: !test not fired. !test a fired !test "a b c" fired !test a b c fired because ignoring extra arguments !test https://www.youtube.com/watch?v=dQw4w9WgXcQ not fired !test <https://www.youtube.com/watch?v=dQw4w9WgXcQ> fired

I'd like to notice that !test https://www.youtube.com/watch?v=dQw4w9WgXcQ worked once. Then, it never fired again (restarting the bot or not). As you can see here http://prntscr.com/j1cwdc it fired once, then it never fired again.
