  Fix race condition in custom library invalidation

During custom function libraries cache invalidation (in
ScriptExpressionFactory) there was a short time window during which
an empty cache could be used by mistake. It was between checking if
the cache is initialized and actually using its content. It is now
fixed.

This should resolve MID-8137.
