Invalid test module state in exunit event

Elixir and Erlang/OTP versions

Erlang/OTP 25 [erts-13.2.2.6] [source] [64-bit] [smp:12:12] [ds:12:12:10] [async-threads:1]

Operating system

Current behavior

In an exunit formatter when setup_all is killed
e.g.

setup_all %{} do
    Process.exit(self(), :killed)
end

the formatter receives events with invalid state

{:test_finished, test = %ExUnit.Test{state: {:invalid, test_module = %ExUnit.TestModule{state: nil}}}}

https://hexdocs.pm/ex_unit/ExUnit.TestModule.html points to https://hexdocs.pm/ex_unit/ExUnit.html#t:state/0 and there nil is ether not started or passed state.

This makes it difficult to print the failure reason for a particular test.

Note: module_finished event emitted later has correct state

Expected behavior

I expect the test module to have :failed state

test_module = %ExUnit.TestModule{state: {:failed, failures}}
