Describe the bug
After introducing #20520 SAS query params are sanitized but it seems like the SAS_EXPIRY_TIME gets modified and it invalidates the provided signature.

To Reproduce
Provide a SAS token with SAS_EXPIRY_TIME without seconds, i.e. se=2021-07-20T13%3A21Z&sp=rwdl&sv=2018-11-09&sr=c&sig=<redacted> that converts the http request query params into se=2021-07-20T13%3A21%3A00Z&sp=rwdl&sv=2018-11-09&sr=c&sig=<redacted> making the signature invalid. This can be reproduced with curl easily.

Generate a valid http request
