Some automation bugs

[PClmnt]

Description

Fixes a couple of issues with automations

• Issue where the selected JS bindings were invalid, updated the backend to support the use of steps context when being passed into a step run
• Stringify the value when an object is passed to the backend log step instead of a string
• Disallow filtering on relationship fields in automation filters as this is not supported.
