When passes input method as nil to Context.new through Irb.new,
ReidlineInputMethod.new is executed and the global internal state of Reline is
rewritten, therefore other tests are failed in the Ruby repository. This
commit changes to use TestInputMethod.

`$HOME/.config` is not writable on CI
because I think tests should not corrupt user's data.
And GitHub Actions CI sets `XDG_CONFIG_HOME`
since `Version: 20210309.1`.

* using the appropriciate exception instead of `break` so that the session
can be continue after the `irb_source` and `irb_load` commands
* suppress extra new line due to one more `#prompt` call

You can use "measure" command to check performance in IRB like below:
irb(main):001:0> 3
=> 3
irb(main):002:0> measure
TIME is added.
=> nil
irb(main):003:0> 3
processing time: 0.000058s
=> 3
irb(main):004:0> measure :off
=> nil
irb(main):005:0> 3
=> 3
You can set "measure :on" by "IRB.conf[:MEASURE] = true" in .irbrc, and, also,
set custom performance check method:
IRB.conf[:MEASURE_PROC][:CUSTOM] = proc { |context, code, line_no, &block|
time = Time.now
result = block.()
now = Time.now
puts 'custom processing time: %fs' % (Time.now - time) if IRB.conf[:MEASURE]
result
}

It caches a path to .irbrc file, which has caused random failure:
```
