I dug a bit and this seems to be happening because of this commit andialbrecht/sqlparse@c1a597e that went out in sqlparse 0.4.3.

I'm not entirely sure if this is revealing a bug in mycli (should it be escaping table names like this if necessary?) or if this is a perfectly find change in behavior, and the test should just be updated to allow the new behavior.
