TreeFromMap Fails for Array of string

[jixiuf]

Describe the bug
got this error

    TestTreeFromMapArray: config_test.go:24: shound not err (0, 0): Can't convert [foo bar]([]string) to []string(slice)

To Reproduce

type testStruct struct {
	Slice []string `  toml:"alice"  `
}

func TestTreeFromMapArray(t *testing.T) {
	tree, _ := toml.Load(`alice = ["foo","bar"]`)
	tree, _ = toml.TreeFromMap(tree.ToMap())

	var result testStruct
	err := tree.Unmarshal(&result)
	if err != nil {
		t.Error("shound not err", err)
	}

}

Expected behavior
should not error.
