New in c# 8
Assert.True(check for null) doesn't give a hint that the obj isnt null
afterwards.
Assert.NotNull does have the compiler hint attribute
could probably use fluentexpression syntax, but resharper doesn't pick
up on the nonnullable hint like vs does.
GeneratorTests: swap FirstOrDefault to First, can keep the fluent style
and resharper gets the hint.
tl;dr : resharper doesn't look at external lib for hints, gotta use
Assert.NotNull or something that doesn't return null
remove unnecessary %25 check (only applicable for gen4 encounters),
unneeded for gen5 method.
add a test case to generate a haxorus for all natures, verify shininess
