[Error] Error parsing reference when using different quotation marks

[goto-loop]

Describe the bug I've been following the documentation for distrobox assemble and noticed that the command fails if both 'single' and "double" quotation marks are used within the same manifest file. If only one type is used, the command runs fine.

To Reproduce Run distrobox assemble create using the following manifest file. Notice the Signal installation uses single and the Spotify installation double quotation marks (commands are copy/pasted from the respective websites):

[testing]
image=debian:latest
pull=true

# Install Signal Desktop
init_hooks=wget -O- https://updates.signal.org/desktop/apt/keys.asc | gpg --dearmor > signal-desktop-keyring.gpg
init_hooks=cat signal-desktop-keyring.gpg | sudo tee /usr/share/keyrings/signal-desktop-keyring.gpg > /dev/null
init_hooks=echo 'deb [arch=amd64 signed-by=/usr/share/keyrings/signal-desktop-keyring.gpg] https://updates.signal.org/desktop/apt xenial main' | sudo tee /etc/apt/sources.list.d/signal-xenial.list
init_hooks=sudo apt update && sudo apt install -y signal-desktop
exported_apps=signal

# Install Spotify
init_hooks=curl -sS https://download.spotify.com/debian/pubkey_C85668DF69375001.gpg | sudo gpg --dearmor --yes -o /etc/apt/trusted.gpg.d/spotify.gpg
init_hooks=echo "deb https://repository.spotify.com stable non-free" | sudo tee /etc/apt/sources.list.d/spotify.list
init_hooks=sudo apt-get update && sudo apt-get install -y spotify-client
exported_apps=/usr/share/spotify/spotify.desktop

This should result in the following output:
