Nick Khyl e07c1573f6 ipn/ipnlocal: do not reset the netmap and packet filter in (*LocalBackend).Start() ... Resetting LocalBackend's netmap without also unconfiguring wgengine to reset routes, DNS, and the killswitch firewall rules may cause connectivity issues until a new netmap is received. In some cases, such as when bootstrap DNS servers are inaccessible due to network restrictions or other reasons, or if the control plane is experiencing issues, this can result in a complete loss of connectivity until the user disconnects and reconnects to Tailscale. As LocalBackend handles state resets in (*LocalBackend).resetForProfileChangeLockedOnEntry(), and this includes resetting the netmap, resetting the current netmap in (*LocalBackend).Start() is not necessary. Moreover, it's harmful if (*LocalBackend).Start() is called more than once for the same profile. In this PR, we update resetForProfileChangeLockedOnEntry() to reset the packet filter and remove the redundant resetting of the netmap and packet filter from Start(). We also update the state machine tests and revise comments that became inaccurate due to previous test updates.
