[Security] Replace exception mocks with actual exception instances.

It is done for two reasons:
* consistency - we use real exception objects in most of the code
* latest phpunit does not like the way we were creating mocks for exceptions (it could be also fixed by letting phpunit to call the original constructor)
removed APC on the CLI for Travis as it does not work well with PHPUnit and Composer anyway
Revert PHPUnit version, revert APC configuration

As documented in http://php.net/manual/en/function.preg-replace.php, we have to use the `$` notation for replacing the backreference

>When working with a replacement pattern where a backreference is immediately followed by another number (i.e.: placing a literal number immediately after a matched pattern), you cannot use the familiar \\1 notation for your backreference. \\11, for example, would confuse preg_replace() since it does not know whether you want the \\1 backreference followed by a literal 1, or the \\11 backreference followed by nothing. In this case the solution is to use \${1}1. This creates an isolated $1 backreference, leaving the 1 as a literal.

While it is true that passing a different core renderer implementation as inline strategy does not make any sense. Typehint the inline strategy here makes it much more complex to decorate the inline strategy (your decorator has to extend the class and overwrite all public methods instead of implementing the interface directly just to pass the typehint). And I have a valid use case for it (which is the reason why I submitted it now), or rather @lolautruche has one in EZPublish: https://github.com/ezsystems/ezpublish-kernel/pull/793

I don't know exactly whether this change should be considered as a bugfix (merged in the upcoming 2.3.13) or a new feature (merged in 2.5). I guess @lolautruche will like us if it goes its way to 2.3.x (EZPublish could bump its requirement to run on 2.3.13+ instead of 2.3.0+ and use a simpler code).

I remember suggesting the change in the initial PR btw, but it was rejecting sayign it does not make sense to use other strategies at that time.
