Edit+ Asset Finder errors and won't load if the Related Asset Metadata Field's value is a Git file ("Physical File") asset

[davidjb]

Problem

Edit+'s Asset Finder fails to load and produces a JavaScript error if the value is set as a Physical File inside a Git Bridge.

To reproduce

1. Create an empty Metadata Schema.
2. Add a Related Asset metadata field to that Metadata Schema.
3. Set that field's default value to be a file inside a Git Bridge (eg 12345:dist/images/foobar.svg)
4. Create a new Site asset.
5. Apply the Metadata Schema to the Site.
6. View the Site in Edit+ and go to the 'Metadata' settings.
7. Click the Select button in the given Related Asset metadata field.
8. Note that the Asset Finder never loads and the browser's console errors:

    onSuccess https://example.com/_editplusapi:3426:8
    _http/http.onreadystatechange https://example.com/_editplusapi:175:8

This Asset Finder for this field is now out of action until you go to another Related Asset metadata field that works, click Select on it, wait for its Asset Finder to load and then go back, clear the Git Bridge default value, and click Select. The Asset Finder will load successfully that time.

Versions

Tested on Matrix 5.4.0.3 and corresponding Edit+ version.
