Broken jinja2 templating in snowflake sql

Currently, Jinja2 templating is done here:

https://github.com/instacart/lore/blob/f4789b1439801cd5171df69d0d63d12060b52999/lore/io/connection.py#L413-L434

And this is how they are called:

https://github.com/instacart/lore/blob/f4789b1439801cd5171df69d0d63d12060b52999/lore/io/connection.py#L168-L169

The problem here is all the args are passed twice, one to jinja2, the other to snowflake connector.

It will break down right here, because nothing could be formated this way.

For example if we want to run

```
lore.io.analysis.execute(filename='somefile', job_type=self.job_type)
```

we will see `processed_params` is not empty and breaks the program here:
