Omit schema name in sql preview after changing table properties

**Is your feature request related to a problem? Please describe.**
When using the table editor to change some properties of a table, (adding attribute, changing attribute name, etc.) the created sql command always includes the schema name. A lot of time, I just want to copy those SQL commands and add them to the Database version control. But then I always need to first remove the schema names (obviously it already happened that I was
tired and forgot to do so).

**Describe the solution you'd like**
Provide an option to disable the adding of the schema name
