Tab completion panics for unrecognized commands

[aw-bib]

It seems that if I use :vertical ro and try to expand rooms via the tab-key iamb crashes

thread 'main' panicked at 'unknown command vertical', /home/arwagner/.cargo/registry/src/github.com-1ecc6299db9ec823/iamb-0.0.7/src/base.rs:868:14

(same for :horizontal ro<tab>).

Thank you for catching and reporting this! It looks like I made the default case for commands to panic when I added this in #44 , but then forgot to change it.
