[crac] RFR: Fix ordering of invocation on Resources [v11]

[Radim Vansa]

> * keeps the original handling of exceptions: afterRestore is called even if beforeCheckpoint throws
> * allows to register a resource in a context that did not start beforeCheckpoint invocations yet
> * registering resource in previous/running context fails the checkpoint but does not trigger exception immediately
>    * instead this will be one of the recorded exceptions and the resource has a chance to fire next time
> * allowed registration of resources can be invoked from other thread without deadlock; illegal registration can deadlock, though
