[coc.nvim] error: UnhandledRejection: request error nvim_eval - Vim:E117: Unknown function: coc#util#valid_state
## Output channel: TexLab

Describe the bug

The following error message is printed whenever I jump to a *.tex window:

[coc.nvim] error: UnhandledRejection: request error nvim_eval - Vim:E117: Unknown function: coc#util#valid_state

Reproduce the bug

• Create file mini.vim with：

set rtp+=~/.vim/bundle/Vundle.vim
call vundle#begin()
Plugin 'VundleVim/Vundle.vim'
Plugin 'neoclide/coc.nvim'
call vundle#end()
let g:coc_global_extensions = ['coc-texlab']

• Start (neo)vim with command: nvim -u mini.vim
• Create a window split
• Open a *.tex-file that has been compiled and has a .log-file
• Leave and enter the file's window with the cursor
• Previously mentioned error should appear

The error seems to be related to the file's corresponding .log-file, because after removing it the error doesn't appear. After restoring the log file the error re-appears.
