Describe the bug / steps to reproduce

The changes added in 1f3e985 introduced a bug. I cannot execute :FzfLua without first executing :FzfLua files or some other command.
I get

E5108: Error executing lua: ...ce/.local/share/nvim/lazy/fzf-lua/lua/fzf-lua/config.lua:987: attempt to co
ncatenate a nil value

I have not fully dug into what this change is supposed to do but I can verify that utils.get_info().cmd returns with nil and the concatenation fails afterward. Adding a nil check before the line or just applying tostring to utils.get_info().cmd solved it for me.

If I follow the call a bit it does something with the last query so it makes sense that it misbehaves when used without anything before that. I'm not sure why it only happens for some commands and not others.

Ty for the report @Norodix, I couldn't reproduce but hopefully 612ee9b is the right fix.

Tested, works for me, thanks!
