zsh config doesn't initialize correctly with shell integration enabled

[roblourens]

Turned on shell integration again, and my zsh configuration still isn't loading correctly, so I dug into it. I have these lines in my .zshrc which come from Prezto:

if [[ -s "${ZDOTDIR:-$HOME}/.zprezto/init.zsh" ]]; then
  echo init
  source "${ZDOTDIR:-$HOME}/.zprezto/init.zsh"
fi

With shell integration disabled, $ZDOTDIR is not defined, and it enters the block. With it enabled, $ZDOTDIR is /var/folders/tx/p0ycbfpj37786p760wwdg6y80000gn/T/vscode-zsh so my config isn't sourced

I guess ZDOTDIR should be unset before we run the init scripts:

vscode/src/vs/workbench/contrib/terminal/browser/media/shellIntegration.zsh

Lines 7 to 16 in f37acd3

	if [ -f ~/.zshenv ]; then
	. ~/.zshenv
	fi
	if [[ -o "login" && -f ~/.zprofile ]]; then
	. ~/.zprofile
	fi
	if [ -f ~/.zshrc ]; then
	. ~/.zshrc
	fi
	unset ZDOTDIR # ensure ~/.zlogout runs as expected
