MT#60864 Fix Sync Email Templates button behavior

The 'Sync Email Templates' button is shown in the Email Templates
page in case some templates is missing for a reseller.
The problem is that the button takes into consideration also
resellers that are already terminated and for which the template
is not needed anymore.

Thus the query has been in fixed in order adding:
r.status != 'terminated'
