Subject: [PATCH] Add spec to the result of Coverage lib for `begin`

Ref: https://github.com/jruby/jruby/issues/8173
This commit is intended to make sure `Coverage` library behaves
the same for the code with `begin`. JRuby had an issue so this
change will help JRuby and other implementations to avoid it.
