FIX: Prompt override error in the Front end

[leongj]

Purpose

Currently, if you try to use the "Prompt Override" in Developer Tools, you will get a Python error coming back in the Chat response. This is because in chatreadretrieveread.py the injected_prompt is not being populated in the prompt_override.format call (as it is in the other cases of the if statement). In this case, injected_prompt is irrelevant, so I have set it to "" as per the un-overriden case.

Does this introduce a breaking change?

[ ] Yes
[x] No
