[lldb] Make TestIOHandlerCompletion more stable and document it 

Instead of relying that three tabs show all completions, we should
show all remaining completions which will always stop the mode
where we show completions. Should fix this test on systems that
somehow have more completions that our normal LLDB (as they
would end up being stuck in the mode where we show completions).
