[ruby/irb] Reset history counter even when @loaded_history_lines is
not defined
(https://github.com/ruby/irb/pull/853)
The issue (https://github.com/ruby/debug/issues/1064) is caused by a
combination of factors:
1. When user starts an IRB session without a history file, the
`@loaded_history_lines` ivar is not defined.
2. If the user then starts the `irb:rdbg` session, the history counter
is not set, because the `@loaded_history_lines` is not defined.
3. Because `irb:rdbg` saves the history before passing Ruby expression
to the debugger, it saves the history with duplicated lines. The number
grows in exponential order.
4. When the user exits the `irb:rdbg` session, the history file could be
bloated with duplicated lines.
This commit fixes the issue by resetting the history counter even when
`@loaded_history_lines` is not defined.
