Fix built in bot commands that have aliases being sent to the backend alias check

[JRMurr]

commands like quote which is a built in alias of quotes will be sent to the back-end to be checked if it is a user created alias.
Commands with aliases look like this

ThiccBot/bot/thiccBot/cogs/quotes.py

Line 36 in af9e24a

@commands.group(name="quotes", aliases=["quote"])

Just need to update this

ThiccBot/bot/thiccBot/cogs/alias.py

Line 18 in 33dfadc

def get_bot_command_names(self):

Should only need to look at 'root' commands, sub commands should not matter since user created aliases can't have spaces
