Minor update to the schema exclude order for the CLI case

[chile12]

Description

• Schema exclusion was performed after applying explicitly included schemata, which resulted in confusing behaviour (especially in the default case, excluding owl when explicitly requested)
• in addition the default schemata directory was not copied to the validate module and therefore not available in the CLI case

How Has This Been Tested?

is covered by the ValidateUtilsTest
