.Site.Data falls back to assets/data when data directory not present in project root

[jmooring]

Works as expected with v0.122.0.
Tested with hugo v0.124.0-DEV-7508a16.

my-project/
├── assets/
│   └── data/          <-- .Site.Data is reading this directory
│       └── foo.toml
├── content/
│   └── _index.md
├── layouts/
│   └── index.html
└── hugo.toml

failing test case

func TestFoo(t *testing.T) {
	t.Parallel()

	files := `
-- hugo.toml --
disableKinds = ['page','rss','section','sitemap','taxonomy','term']
-- assets/data/foo.toml --
content = "I am assets/data/foo.toml"
-- layouts/index.html --
|{{ site.Data.foo.content }}|
	`

	b := hugolib.Test(t, files)

	b.AssertFileContent("public/index.html", "||")
}

We uncovered this problem when assets/data contained a text file (there's nothing wrong with that), resulting in this error when calling .Site.Data

Error: error building site: failed to load data: failed to load data: "/home/user/project/assets/data/foo.txt:1:1": unmarshal of format "" is not supported

Apologise a little for not fixing this sooner, I have fixed issues in a "first see" order, so to speak, and didn't see this until today. I have a fix on its way.
