Remove urlencode from srcset calculation function

[hugosolar]

Description of the Change

This change fixes an issue with URLencoding we've seen in our sites. Blob URLs are being encoded in the windows_azure_storage_wp_calculate_image_srcset function which causes wrong URLs when displaying those in the browser.

Removing those encoding, fixes the issue and return a valid URL

How to test the Change

• Upload an image to the blob storage
• Display the image in the frontend using wp_get_attachment_image. This will cause, the plugin hooks in through the wp_calculate_image_srcset filter
