[Console] fixed style creation when providing an unknown tag option

Some tests relying on timings and external network resources were not
reliable and occasionally made builds on Travis fail.
return empty metadata collection if none do exist

The PropertyMetadataContainerInterface defines that the method
getPropertyMetadata() has to return an empty collection if no
metadata have been configured for the given property. Though, its
implementation in the ClassMetadata class didn't check for
existence of such metadata. This behavior led to unexpected PHP
notices when validating a property or a property value of a property
without any configured constraints (only affects the new 2.5 API).
Additionally, the getMemberMetadatas() didn't check for existing
array keys as well which has also been fixed.

When formatting a string, the console ignore style it cannot parse. But if a string looks like an option (`<setting=value>`) for instance, instead of displaying the text as is, it currently throws an exception.

ToDo

 * [x] Fix Tests

Looking for feedback on this early PR.

This adds a config option that disables the PHP GC method call from doing anything,
It also means that the write method sets up the auto expiring index.

In the [latest merge from 2.3 into 2.4](/symfony/symfony/commit/3bed1b7988e94a897a64c6a2ad3bf70bde9005c1), the changes from 6cf5e0812e6f20d60acbc0324abf96475e89b6ef in 2.4 got lost. This PR brings back these changes and backports them to 2.3.

The change is BC, because the former value `true` of the `$prettyDateTime` will be cast to `1`, which corresponds to the `PRETTY_DATE` format constant.
