[vim/vim] Error detected while processing... when startup vim with -u option (Issue #14560)

[Shinya Ohyanagi]

I found startup vim with -u option to specify vimrc raised error.

Steps to reproduce

1. Add below plugin in to ~/.vim/pack/test/opt/sample/plugin.vim

let s:items = [
  \ 'foo',
  \ 'bar',
  \ ]

function! s:sample() abort
  echomsg s:items->join(' ')
endfunction

command! Sample :call s:sample()

2. create .vimrc

packadd sample

3. start vim with -u option

vim -u ~/.vimrc

4. Error raised

s_ohyanagi@a961a4e1ba1d:~$ vim -u .vimrc

Press ENTER or type command to continue

5. Enter vim and exectute :Sample

Error detected while processing function <SNR>2_sample:
line    1:

5. when I start vim without -u option, error not raised and can execute command
