📄 Description

Found while working on #541. Prior to this change, if you called the list method in PostgresSaver with an empty configurable object (e.g. saver.list({ configurable: {} })), you'd get back no results. This was due to a small error in the branching logic for building up the WHERE clause that is used to query for checkpoints.

Also, like in #576, I noticed that the LIMIT clause was being directly concatenated into the query without sanitization (a potential SQL injection vulnerability), so I went ahead and fixed that in this commit as well.
