Multipass won't start if systemd-resolved is disabled

**Describe the bug**
Mulipassd does not start unless I install snapcraft --classic

**To Reproduce**
How, and what happened?
1. Multipass service does not start

**Expected behavior**
What did you expect to happen? After installation multipass service fails to start

**Logs**
No logs are created

**Additional info**
- OS: POP os 20.01
- `multipass version: 1.6.2`
- `multipass info --all`
info failed: cannot connect to the multipass socket
Please ensure multipassd is running and '/var/snap/multipass/common/multipass_socket' is accessible

**Additional context**
Service starts if I install snapcraft --classic

Start by reproducing the failure on Pop!_OS 20.01 with systemd-resolved disabled, using the reported Multipass 1.6.2 installation and checking why multipassd creates no logs or accessible socket. Done means the Multipass service starts without installing snapcraft --classic and `multipass info --all` can connect to the socket.
