FR#1513 Correct template variables and TRY symbol

Change I6409578a517 altered the template variables used in thank
you messages. Some templates slipped through our alter though. So,
fixing those up.

Also; TRY has a symbol that's unprintable in most fonts, so removing
it for a fallback to just the ISO code.
