SnowflakeHandler in v1.0.0-RC1 ignores database and schema in some cases

[janblom]

Describe the bug
When running WhiteRabbit against a Snowflake instance with multiple databases and/or schema's, tables are not always properly identified by the correct database & schema, leading to crashes and/or errors reporting non-existent tables or columns.

To Reproduce
Steps to reproduce the behavior:
This requires a Snowflake instance with multiple database and/or schema's and duplicate column names across tables
to reproduce. Bug fixes will need to be field-tested with instances that have these features.

Expected behavior
Snowflake tables and columns should always be identified by the correct database and schema.

Desktop (please complete the following information):

• OS: any
• Version v1.0.0-RC1

An additional fix was applied to prevent an exception that was reported by a tester ("java.lang.ClassCastException: class org.ohdsi.rabbitInAHat.dataModel.Table cannot be cast to class java.lang.Comparable (org.ohdsi.rabbitInAHat.dataModel.Table is in unnamed module of loader 'app'; java.lang.Comparable is in module java.base of loader 'bootstrap')
