Description:
------------
Exceptions nesting a previous exception result in misleading error-reports.

In the test script below, Foo was actually caught and nested in an uncaught Bar.

The resulting fatal error errorneously suggests, that Foo was not caught.

Test script:
---------------
class Foo extends \Exception {};
class Bar extends \Exception {};

try {
    throw new Foo('Foo-message');
} catch (Foo $e) {
    throw new Bar('Bar-message', 4711, $e);
}

Expected result:
----------------
Fatal error: Uncaught exception 'Bar' with message 'Bar-message' in test.php on line 8

Foo: Foo-message in test.php on line 6

Call Stack:
0.0002     269440   1. {main}() test.php:0

Bar: Bar-message in test.php on line 8

Call Stack:
0.0002     269440   1. {main}() test.php:0

Actual result:
--------------
Fatal error: Uncaught exception 'Foo' with message 'Foo-message' in test.php on line 8

Foo: Foo-message in test.php on line 6

Call Stack:
0.0002     269440   1. {main}() test.php:0

Bar: Bar-message in test.php on line 8

Call Stack:
0.0002     269440   1. {main}() test.php:0

No, not really.  The Foo instance has been passed as $previous
argument to the Bar constructor, so the first exception is a Foo,
and the next exception is a Bar.  And the stacktrace displays the
exceptions in that order.
