fix: create property default value assignment

[gramian]

What does this PR do?

This change syncs the the assignment of a default value in CREATE PROPERTY to the way it is done in ALTER PROPERTY (see https://github.com/ArcadeData/arcadedb/blob/main/engine/src/main/java/com/arcadedb/query/sql/parser/AlterPropertyStatement.java#L96 ).

Motivation

Using sysdate in a default value was evaluated at property creation time not at record creation time.
