pipenv's Trivia patch to make tomlkit dump toml's inline table about tomlkit

ping @frostming , can you confirm you are the author of this?

I've confirmed this patch is needed by pipenv.

Without it, test_uninstall.py::test_normalize_name_uninstall fails at assert "# Inline comment" in contents, with the entire line removed.

Now I understand the patches effect a bit better, this feels like it isnt a complete patch, as that inline comment after an entry probably needs to be removed with the entry in some cases, and it should be up to the caller whether 'dangling' comments should be kept, so some mechanism needs to be added to allow the caller to control this. But that is just a guess, and I'd appreciate feedback from @sdispater about whether this patch is acceptable as-is .

this patch is authored by me to preserve the comment when an entry is removed. It is required by pipenv in the regressiin cases. However it is not always expected
for a general toml document. Cases are user may want to remove the comments together with the line it is bound to. So I just patch it in pipenv vendor but leave it to original creator how to design it.
