[BUG] unexpected error when printing a variable name before variable definition, level 2 and 3

[OnnoEbbens]

Describe the bug When you define a variable in line 2 and you want to print the variable name as text in line 1 you get an error.

Paste the Hedy code & level This code in level 3:

print I love animals
animals is dog, cat, mouse
print animals at random

raises this error:

We can't run your program.

You cannot use the command print with animals because it is a list. Try changing animals to text or a number.

This code in level 2 or 3:

print I love animals
animals is dog
print animals

raises this error:

Something went wrong while running the program.

name 'animals' is not defined

Expected behavior Variable names that are not defined yet should be printed as text. Although I can imagine that this is hard to implement on the interpretation side. If it to hard an appropriate error for these cases would be nice.

Yeah, we know! This is a duplicate of #165 but it is really hard to fix since it involves program analysis to see where a variable is used. I will try to work on this over Christmas
