When you enable the IPN notifications in your Paypal account configuration,
the default IPN URL is mandatory.
You are therefore obliged to put the IPN feedback URL of Odoo
in this default URL, even if this is not used because
each transaction done by Odoo specifies the URL to which the IPN
notifications must be sent.
Because of this, if you use your Paypal account
for something else, e.g. Ebay, you receive
notifications of payments for these other transactions,
that have nothing to do with Odoo.
In such a case, Odoo returned an HTTP error status code (e.g. 500),
because Odoo couldn't find the given transactions, and
then Paypal sent emails to the Paypal owner
to tell the IPN feedback was failing. Eventually, after
several fails, Paypal automatically disabled the IPN
notifications of the given account.
With this revision, we now avoid to raise the Validation errors
in the case of the IPN feedback, and just logs it,
to avoid Paypal to sent emails to
the owner and to automatically disable the IPN notifications
if it receives transactions from other services than Odoo.
