PGSchema::migrate does not work in Laravel 5.2.41 onwards

[otepas]

This Laravel PR (laravel/framework#13008) has changed the way Laravel checks if a table exists. Now the schema defined in config/database.php file is always used to check if the table exists there.
This is used by migrate to check if the migrations table exists.

PGSchema::migrate($newSchemaName) does not work because $newSchemaName is not used to check the right migrations table.
