Fix Raidus remove doesn't update main menu (#95)

### Problem
Right clicking a bot in raidus will log the bot out but the main menu
doesnt update to show the bot is logged out

### Fix
Use .playerbot bot remove instead of logout for Raidus bot removal
This updates the main menu to show the bot is now offline
