POCKET-35: Do not automatically set printSchema but rather wait for its existence to enrich the builder

Before the change, we are setting printSchema to true for any MSSQL template regardless of whether or not we can retrieve a schema name.

Some products are not schema name aware, like Confluence.

Rather than automatically require print schema on any MSSQL SQLTemplate, we will wait for the enrichment to set the flag for us depending on whether or not a schema name is available via the product schema provider.
