UTA database recreates schema on startup

[zealws]

Describe the bug

The UtaDatabase class recreates the schema in the create function.

This results in the schema being recreated every time the class is instantiated, regardless of whether the schema exists or not.

This is most clearly an issue if the UTA user doesn't have permission to recreate tables, because it results in an error, even if the schema is already setup correctly.

Steps to reproduce

Instantiate PostgresDatabase (or use any of the functions that rely on it)

Expected behavior

If the schema already exists: it uses the existing schema without modifying it.

Current behavior

It recreates the schema, regardless of if it exists or not.
