Not consistent table naming when using InnerJoin()

[WestleyK]

When using InnerJoin(), pika will sometimes rename the table name in the query. This can cause an issue when you want to filter by a value in that table, you need to manually debug the query to see what pika changed the table name too.

Notice join_model_foreign vs joinModelForeign.
