default shield prevents uploading image for Uphold KYC

[LaurenWags]

Description

Follow up to #4139

When I go to upload an image to complete KYC on Uphold, I get a message that I'm not uploading a supported file type. However, if I change my default FP setting to allow, then I can proceed.

Steps to Reproduce

1. Go to uphold.
2. Create an acct and begin KYC.
3. When you go to upload an image of your driver's license, you will be told your file type is incorrect.
   Note - when testing this, do complete the entire KYC process (uploading all docs and a selfie, and any other information as needed).

Actual result:

When I go to shields I see this:

Expected result:

KYC should work easily without shield changes for users.

Reproduces how often:

easily
