Get custom schema fix (SAP#225)

The custom schema is not only accepting custom schemas, it is accepting
any syntactic valid schema.
That's why [these
lines](https://github.com/SAP/scimono/blob/adebc03c26dbda55366849a477b4bcfb26e574e2/scimono-server/src/main/java/com/sap/scimono/callback/schemas/SchemasCallback.java#L37-L44)
are effecting that every syntactic valid schema is handled like a custom
schema. Core schemas will not be found.

In my understanding the core schemas are not custom schemas.
