Message to activate username appears even if you already have username

[Catrya]

When someone is going to create a new order, the bot must check that the person has an active username, otherwise it will send a message asking to activate it

However, every time you create an order, the bot sends the message that you activate your username in the channel where you publish it instead of sending it as a direct message, even if you already have an active username.

In case you do not have a username and try to take an order, the bot will also send the message to the channel where you tried to take the offer instead of sending it as a direct message.

I think that behavior appeared after this fix: #408
