To install an assistant, sam runs `bash -c 'sh setup.sh'` - which breaks venv

What's the issue?

Venv activation requires to be run in bash to work, but sam runs bash -c 'sh setup.py' and sh is a symlink to dash on a lot of systems (ubuntu and newer raspbians at least) and that breaks venv activation.

Use Cases Impacted

Assistant install and update

How to reproduce

Run sam install assistant to a system with dash as sh

Expected behavior

Should install the assistant without errors

Version and Environment 0.63.3 / Lubuntu 19.04

Additional information

Workaround

Symlinking sh -> bash fixes this or just editing /usr/local/lib/node_modules/snips-sam/lib/session/ssh.js to simply run setup with bash directly.
