Potential fix to parcel bundling issues when asset parent & commonBundle types differ

#294 #326
This PR potentially fixes the issues mentioned above. It does the following
case (i):
If the below is true => i.e both types are the same (parent Bundle is JS and commonBundle is also JS) move it the common ancestor.

if (
          asset.parentBundle !== commonBundle &&
          asset.parentBundle.type === commonBundle.type
        ) {
          this.moveAssetToBundle(asset, commonBundle);
          return;
        }

case 2:
If they aren't the same, for eg: parentBundle is JS and commonBundle is HTML. Then allow it to continue further so that it adds this asset to the immediate parent.

case 3:
If both parent bundles are equal, then just return.

if (asset.parentBundle !== bundle) {
