Steps to reproduce:
M-x slime
M-x slime
"Create an additional *inferior-lisp*? (y or n)" -> y
,quit in the new REPL
Currently there's no default connection, so the next Slime command with an RPC call asks for switching to a new default.
At the other REPL, M-. on DEFUN.
"No default connection selected. Switch to <foo>?"
Now, when you answer that question with no, it asks the question again, and again, and after a few times (always negating the question), it performs the M-. in the non-selected connection even though it shouldn't.
