Credentials - Not prompted correctly when there are multiple credentials

[sangee2004]

gptscript version - v0.0.0-dev-656ae77b-dirty

Steps to reproduce the problem:

1. Execute the following script that have tools from github.com/gptscript-ai/search/google

% cat google_search.gpt
tools: github.com/gptscript-ai/search/google, sys.http.html2text?

You are an expert web researcher with access to the Google Search API.

What are some low-calorie, keto-friendly lunch recipes? How about dinner recipes? How many calories are in each one?

2. I see duplicate prompts and also see some information already prefilled as well and the script never exits.

gptscript --disable-cache google_search.gpt

Expected Behavior:
Should be prompted for credentials properly and the script execution should succeed.
