[notification] avoid leaking cnxsets (closes #3243810)
When sending notifications, we get each recipient as either an email
address or a CWUser. In the latter case, we create a temporary session
for that user and use it to send the mail. However, if we later decided
to not send the mail after all, we'd leak the session and its cnxset.
Add a try block inside the loop to make sure the temporary sessions are
closed properly.

CubicWeb features
=================
This page tries to resume features found in the bare cubicweb framework,
how mature and documented they are.
:code maturity (CM):
- 0: experimental, not ready at all for production, may be killed
- 1: draft / unsatisfying, api may change in a near future, much probably in long
term
- 2: good enough, api sounds good but will probably evolve a bit with more
hindsight
- 3: mature, backward incompatible changes unexpected (may still evolve though,
of course)
:documentation level (DL):
- 0: no documentation
- 1: poor documentation
- 2: some valuable documentation but some parts keep uncovered
- 3: good / complete documentation
