fixes ISSUE-44892: on DB creation config scripts are applied in two steps

When creating database, the database model was created in two steps:

1. model creation without taking into account config scripts
2. config script changes (model and data) were applied

This can cause different problems.

Now the process is more like:

1. read in memory model without config script changes
2. read config script model changes and apply them in memory model
3. create complete model in DB
4. read and apply data in DB without config script changes
5. read and apply in DB data config script changes
