fix(org): make sure org-reveal is called in the right buffer

Sometimes, `org-reveal` is called in the wrong buffer which throws an
error.  For example, `org-link-open-from-string` creates an temporary
org-mode buffer that gets killed very quickly which means that
`org-reveal` gets called in a different buffer.  I have also had issues
with org-reveal getting called in the org-roam buffer, which is why this
commit also saves the buffer it was called in.
