Support using Postgres database without public schema

Kyoo's version

4.6.0

What happened?

Unable to use database/user without public schema. The first pass of the migration container runs successfully and the application starts. However if the migration container runs again, it errors out with the following message.

Failed executing DbCommand (11ms) [Parameters=[], CommandType='Text', CommandTimeout='30']
CREATE TABLE "__EFMigrationsHistory" (
    migration_id character varying(150) NOT NULL,
    product_version character varying(32) NOT NULL,
    CONSTRAINT pk___ef_migrations_history PRIMARY KEY (migration_id)
);

When running using the public schema, migration container completes without error even on restart.

No migrations were applied. The database is already up to date.
Done.

the transcoder now uses it's own schema, the backend will be reworked in v5 (and won't use the public schema)
