Fix potential out of bounds index in test

[juusom]

While working on merging master to #81 I noticed that the process function in the integration tests assumes that indices 100 and 1000 exist. Currently, the event_count that gets passed into the method is 1000 + rand(50). rand(50) may return 0, yielding a count of 1000 and a maximum index of 999.

This should make the function a bit safer.

Thanks Juuso, indeed it's me to blame.
While your code fixes the issue it requires extra 🤔 could we just hard-code 999:

Suggested change

	[0, 100, 1000].each do |idx|
	idx = [idx, event_count - 1].min
	expect(events[idx].get('sequence')).to eq idx
	end
	[0, 100, 999].each do |idx|
	expect(events[idx].get('sequence')).to eq idx
	end

Sure, I don't mind. I just figured it would make sense to have a bit more generic approach because this way the function requires to input to be >=1000.
