Pass mandatory argument to initgame in tests

[giordano]

PR #38 added a new mandatory argument to initgame, which however isn't used in
tests.

[aviks]

There is a default to that argument, so this should not be required?

Separately, I havent figured out a way to run the game loop in a headless system, so we don't have CI.

There is a default to that argument

Uhm, no:

GameZero.jl/src/GameZero.jl

Line 198 in 26b1a22

function initgame(jlf::String, external::Bool)

rungame has a default value for external:

GameZero.jl/src/GameZero.jl

Line 179 in 26b1a22

function rungame(jlf::String, external::Bool=true)

Maybe a better solution is to give a default value of external (true?) to initgame as well?

[aviks]

Ah, OK, indeed. Actually, this is correct, initgame should not have a default, IMO. I'll add some comments to remind myself what is happening.
