[BUGFIX] Fix serialization of loggers

Only dealing with PHP file resource in writers is not
enough to properly initialize a logger on wakeup.

A logger has to log with a new request IDs and possibly completely new writers
and processors due to configuration changes in the meantime.

Therefore the __sleep and __wakeup methods are removed in the FileWriter
and new methods are added to the logger instance to make sure a
wakeup will have a correctly configured logger instance.
