Followup fix to custom session save handlers

2d9885c introduced some regressions. This addresses those.

* Don't throw return type notice or session write failure when in an exception
* Fix tests to properly return true/false since null is no longer falsy/successy
* Rerecord a few tests to accomodate difference in raised warnings

Fix handling of session user module custom handlers.

According to the documentation, returning TRUE from
user based session handlers should indicate success,
while returning FALSE should indicate failure.

The existing logic relied on casting the return value
to an integer and returning that from the function.
However, the internal handlers use SUCCESS/FAILURE
where SUCCESS == 0, and FAILURE == -1, so the following
behavior map occurs:

return false; => return 0; => return SUCCESS
return true; => return 1; => return <undefined>

Since the session API checks against FAILURE,
both boolean responses wind up appearing like "not FAILURE".

This diff reasserts boolean responses to behave as
documented and introduces some special handling
for integer responses of 0 and -1 so that code can be
written for older and newer versions of PHP.
