fix(client): no panic on empty inspector (#1768)

* fix(client): no panic on empty inspector

* fix: clippy warning

Although I am not that happy with this clippy rule.
I am old school and we learned to put the most likely path first.
Back then compiler optimizations were not too great and cache prediction
was better handled this way.

* Update atuin/src/command/client/search/interactive.rs
