Table arrays containing primitive arrays unnecessarily serialize inline.

[Evan-Walden-ATS]

The following TOML file:

[[table_array]]
primitive_list = [4, 5, 6]

When run through the functions Toml.ToModel & Toml.FromModel as follows:

var toml = "[[table_array]]\nprimitive_list = [4, 5, 6]";

var model = Toml.ToModel(toml);
var tomlOut = Toml.FromModel(model);

Results in the following output:

table_array = [{primitive_list = [4, 5, 6]}]

I believe this may be a bug, as it appears that the serialization code otherwise prefers to use the non-inline style wherever possible.

I think that it's not really a bug but I have pushed a fix ffcc734 to mitigate it.

The problem is that TOML is not a roundtrip-able serialization format. There will be other cases like this.

If you need to be roundtrip-able, it would require to use only the Syntax tree but not the model tree (that doesn't know/store any information about the way things should be serialized back).
