Env: appliance-10-240-0-13

Preconditions:

1. Two different images with completely identical names.
2. An existing product.

Steps:

1. Sign in as an admin at /admin
2. Navigate to Products > PDP > Media
3. Create album with any valid name
4. Upload 1st image of 2 mentioned in preconditions
5. Upload 2nd image.
6. Once upload is done - check these 2 images. Refresh the page and check them again.

Actual result: duplicated image names aren't appended with (1)...(n), which results into one image being overrode with another one.
Expected result: if image name of a just uploaded image duplicates name of an image that already exists in the album, new image name should be appended with a number.
