* Consolidate logic for determining whether or not session is interactive
into a single function, is_interactive()
* Increase test coverage
I wasn't able to find a good way of simulating running a backgrounded test with CI since the
whole test is essentially run not in a TTY, which is similar enough to cause the new is_interactive()
function to always return false.
