picongpu-completion.bash fails in screen session

[PrometheusPi]

When using pic-create auto-completion in a screen session, the auto-completion fails with a:

bash: _init_completion: command not found

error. Outside the screen session, the same workflow works.

For me it works...

offline investigation with @finnolec:
Auto-completion of flags provided by pic-build still works for me.

found by @finnolec:
When sourcing the system bash_completion via:

source /usr/share/bash-completion/bash_completion

everything works as expected.

This here

if [ -f /etc/bash_completion ]; then
    . /etc/bash_completion
elif [ -f /usr/share/bash-completion/bash_completion ]; then
    . /usr/share/bash-completion/bash_completion
fi

should work more reliable in case the bash_completion file is in a different directory. The /usr/share/bash-completion/bash_completion path should work on hemera :) You can add this part to your .bashrc
