Asset field contents broken when choosing "Discard and use existing file"

[gavynd6]

Bug description

If you upload a duplicate file into an Asset field, it will ask how you want to fix the conflict. If you select "Discard and use existing file", the field now references an incorrect text path, rather than loading in the existing asset. When you then try to save the entry, the validation fails as it can't find the asset.

How to reproduce

1. Attempt to upload a known duplicate file into an Asset field

2. Select "Discard and use existing file" from the Fix menu

3. The asset is replaced with a text path, not the actual file

4. Attempt to save the entry. A validation error will occur:
   Asset [undefined::user.png] not found
