Fix cloud user information context when loading a new cloud project

[nirvn]

This PR fixes missing cloud user details context for expressions when loading a new cloud project.

Long story short here, when we load a new cloud project, the cloud user information having not been saved before is simply not written, and therefore the cloud user information changed signal returns empty values.

Thanks for the fix! Code looks good. I have not tested myself, but the explanation sounds good!

To backport manually, run these commands in your terminal:

# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add .worktrees/backport-release-3_3 release-3_3
# Navigate to the new working tree
cd .worktrees/backport-release-3_3
# Create a new branch
git switch --create backport-5587-to-release-3_3
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick ee92f0b903d6f2eee69271becae38ac09b0b3a70
# Push it to GitHub
git push --set-upstream origin backport-5587-to-release-3_3
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-release-3_3

Then, create a pull request where the base branch is release-3_3 and the compare/head branch is backport-5587-to-release-3_3.
