BUG: Helm chart sync job does not fetch charts in fresh install

[prakarsh-dt]

Helm chart sync job doesn't fetches charts in fresh install because it fails as migration is still under process.

Checklist:

• I've searched in the docs and FAQ for my answer
• I've included steps to reproduce the bug.

To Reproduce

Do a fresh installation without any integrations.

Expected behavior

Charts should start appearing as soon as devtron installation is complete.

Current behavior

No Helm charts appear.
