Description

When I use the ButtonBuilder in a private message and the user react to answer it the buttonMenu use the function event.getGuild (ButtonMenu.java:135). This function call is try getting the guild from a TextChannel (GenericMessageEvent.java:126) and not from a private channel. This ends in a IllegalStateException: This message event did not happen in a text channel
