Removing \includeonly from g:vimtex_include_indicators defaults

[AsbjornPreuss]

Description

As suggested in comments of #2519 \includeonly is does not actually include any files in the document, but only defines which files of actual \includes, that are to be included in the compilation. Having includeonly in g:vimtex_include_indicators results in files and TODOs to be shown twice in the vimtex-toc.

Steps to reproduce

1. Change minimal.vim to point to installation of vimtex
2. nvim -u minimal.vim minimal.tex
3. Open vimtex toc (\<leader>lt) minimal.zip

Expected behavior

Actual behavior

Do you use a latexmkrc file?
