Fixed Makie error in interactive_orbitdiagram

[jonathanfischer97]

I fixed the Makie.Layout error I raised in JuliaDynamics#237 by removing that qualifier from the deactivate_interaction! call.

Other changes that can be ommitted upon review

• I removed some display(figure) calls because they seemed unnecessary and aren't shared by the other interactive plotting scripts.
• I preallocated the Vector{Point2f} in the first minimal_normalized_od method because the length is known at compile time (the other method has conditional push so left it as is)
• Finally, I added a testset and a test for calling this plotting function. Not sure if you guys don't use a Test.jl based CI for a reason or was just never implemented. The test fails with an error with the prior code but passes now.
