Bug 25130: Reason for accepting/rejecting a suggestion is not visible when viewing (not editing)

The patch adds the suggestion management reason to the display when
viewing a suggestion.

To test:

1) Edit a suggestion and assign a reason for accepting it.
2) View the suggestion (/cgi-bin/koha/suggestion/suggestion.pl?suggestionid=XX&op=show, replacing XX with your suggestion ID)
3) Under suggestion management, the reason you've just assigned does not
display.
4) Apply the patch
5) Check the display again - the Reason should now be visible directly
under the status.
