Multipass daemon gets stuck if `vm->current_state()` throws

Multipass daemon gets unresponsive if the `current_state()` call throws in the following code block:

https://github.com/canonical/multipass/blob/c3ec76c294e984bb344fb22aecae8761a3d522c0/src/daemon/daemon.cpp#L1391-L1393

The `current_state()` is not marked with `noexcept`, so handling the possible exception or marking the function as `noexcept` can mitigate the "stuck" situation.

Start in src/daemon/daemon.cpp at lines 1391-1393, where vm->current_state() is called. Review how exceptions from this call affect the daemon and determine whether the intended mitigation is exception handling or marking current_state() noexcept. Done means the daemon no longer becomes unresponsive when current_state() throws.
