thread 'main' panicked at 'called `Option::unwrap()` on a `None` value'

Currently, I get:

$ scryer-prolog -f
?- read_term(T, [variable_names(VNs)]).
T.
thread 'main' panicked at 'called `Option::unwrap()` on a `None` value', src/machine/machine_state.rs:587:76
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

This is present both in master and in rebis-dev

Thank you, this works correctly now!
