Fix: Aliased command not received arguments

[arispati]

I've the same issue with #837 that using alias command not received arguments.

After checking, it turns out that the problem is in the regex in the prepareRegex function in the Telegram\Bot\Commands\Command class.

Example:

class ExampleCommand extends Command
{
    protected $name = 'example';
    protected $aliases = ['e'];
    protected $pattern = '{code}';
}

/example text

%/example(?:@.+?bot)?\s+?(?P<code>[^ ]++)%si

/e text

%/example(?:@.+?bot)?\s+?(?P<code>[^ ]++)%si

as you can see, the regex use command name instead of the alias name
