Bug 22511: (QA follow-up) Refactor status description in templates

Bug 22511: (QA follow-up) Refactor status description in templates

Test plan:

Before this patch, some accounttypes does not show status (for example
        voided payment)

After this patch, the status is always generated - defaults to empty
string

This behaviour should be same in intranet and opac

In OPAC templates there was even bug (used variable account instead of
        ACCOUNt_LINE), so the status was not shown at all
