VM fails to complete start from a suspended state

[ricab]

Describe the bug The VM starts, but before the start RPC is finished, Multipass tries to sync its clock and there is an exception that goes through Qt code, leaving the daemon in a bad state.

To Reproduce How, and what happened?

1. multipass launch -n foo
2. multipass suspend foo
3. multipass start foo

The last command will keep spinning. After a ctrl+c, I can't reach the daemon anymore:

$ multipass ls
list failed: cannot connect to the multipass socket
