Subject: [PATCH] (ruby-ts-add-log-current-function): Fix when between two
 methods

* lisp/progmodes/ruby-ts-mode.el
(ruby-ts-add-log-current-function): Fix the case when point is
between two methods.  'treesit-node-at' returs the 'def' node of
the method after point in such case, so it behaved like point was
inside the method below.

* test/lisp/progmodes/ruby-ts-mode-tests.el
(ruby-ts-add-log-current-method-outside-of-method):
Update the test case.

* test/lisp/progmodes/ruby-mode-tests.el
(ruby-add-log-current-method-outside-of-method):
Mirror that change.
