Common.credentials confusion

[lifeBCE]

Sometimes Common.credentials is an object and sometimes a string. All supporting logic seems to depend on this being an object so we need to rework this to ensure it is always an object. The setter defined in common.js shows:

Common.cacheCollection.account.cloud_credentials = JSON.stringify(val);

So every time the application does:

Common.credentials = data.account.cloud_credentials;

We get a string assigned.

If we want to keep this as a string representation of an object, we need to update all supporting logic to call JSON.parse before attempting to iterate.
