Contract notification 'Period End' or 'Period End + Notice' : missing fields & php errors

[blerohellec]

v 0.85 or 0.90
When notification 'Periodicity' or 'Periodicity Notice' is used for contracts, with the default notification template 'Contracts', some fields are missing in the notification (name, number and type of contract) and some php errors are generated. Extract from php-errors.log hereafter.
In inc/contract.class.php, function cronContract, variable $contracts passed to raisedEvent (near line 1135) is not fully initialized in the cases mentionned above.
