|EntityBaseSaveAsync Method (IPredicate)|
Async variant of Save(IPredicate)
Saves the Entity class to the persistent storage. It updates or inserts the entity, which depends if the entity was originally read from the
database. If the entity is new, an insert is done and the updateRestriction is ignored. If the entity is not new, the updateRestriction
predicate is used to create an additional where clause (it will be added with AND) for the update query. This predicate can be used for
concurrency checks, like checks on timestamp column values.

Predicate expression, meant for concurrency checks in an Update query. Will be ignored when the entity is
new. Overrules an optional set ConcurrencyPredicateFactory.
true if all changed fields were successfully persisted to the database, false otherwise
|ORMQueryExecutionException||When an exception is caught during the save process. The caught exception is set as the
inner exception. Encapsulation of database-related exceptions is necessary since these exceptions do not have a common exception framework
Do not call this routine directly, use the overloaded version in a derived class as this version doesn't construct a
local transaction during recursive save, this is done in the overloaded version in a derived class.
