fix(editor): HTTP request node showing warning about credentials not set when they are set

[RomanDavydchuk]

Summary

If you have a workflow with a HTTP request node that has Authentication set to Predefined Credential Type and a valid credential selected, and then go look at the one of the workflow's execution, you'll see a warning about the credentials not being set in that node:

but it actually has credentials. The issue is that once you open the execution, the FE does not fetch all of the credentials for the current workflow. This PR fixes that by adding a call to load credentials for the opened workflow
