Fixed issues #4134 undefined array index label_use_default in Mage_Catalog_Model_Product_Attribute_Backend_Media

[empiricompany]

Description (*)

The error occurs only when creating a new product.
This patch skips the PR modification for supporting image labels in the case of a multistore (#2481) since there is no option to use the default label (the product must be created first) and executes the original code to avoid the error.

1. Fixes Error when saving product with image without description #4134

Manual testing scenarios (*)

1. Create a new product
2. Upload an image without a label
3. Keep image label empty
4. Set default for Base Image, Small Image and Thumbnail
5. Save

I have also re-tested multistore labels #2481 and still works correctly.
