Error on VimtexEventCompileSuccess when g:vimtex_view_use_temp_files = 1 and g:vimtex_view_method has not the default value

Issue

Thanks for this great plugin! I'm getting the following error since commit 7c3061f. With the options g:vimtex_view_use_temp_files = 1 and some non-default value for g:vimtex_view_method (e.g., 'zathura'), when compiling a LaTeX document this error message pops up:

Error detected while processing function <SNR>43_callback_continuous_output[6]..
vimtex#compiler#callback[26]..User Autocommands for "<buffer=1>":
E492: Not an editor command: VimtexEventCompileSuccess call b:vimtex.viewer.copy_files()

minimal.vim

set nocompatible
let &runtimepath  = '~/.vim/bundle/vimtex,' . &runtimepath
let &runtimepath .= ',~/.vim/bundle/vimtex/after'
filetype plugin indent on

let g:vimtex_view_use_temp_files = 1
let g:vimtex_view_method = 'zathura'  "error also occurs with the values 'skim' or 'mupdf'

Sorry, you are right. I've updated the related code. I think it should work as expected now.
