`apply0` crashes on function with inputs

[met4000]

Issue type:

• :bug: Bug

---

Short description:

apply0 on a function with inputs causes a crash.

Steps to reproduce the problem:

1. Make a function with inputs and an output, e.g. function f(v) { return 1; }
2. apply0 the function and put the output in a display panel
3. Crashes, and upon adding/removing a cable after reloading the world (removing and re-inserting variable cards into displays doesn't crash and doesn't update display panels - I assume that behaviour is intentional to allow people to remove the bugged cards)

Expected behaviour:

An error instead of a crash.
