Arti is unable to reconstruct circuit after internet connection is restarted

Summary

Arti is unable to automatically reconstruct a circuit after internet connection is turned off and back on. For example, if WiFi is turned off and turned back on, Arti is unable to reconstruct a circuit until Arti is manually restarted. Arti gets stuck in a loop with the following messages:

WARN#033[0m #033[2marti::socks#033[0m#033[2m:#033[0m connection exited with error: error: operation timed out at exit
Unable to select a guard relay: No usable guards. Rejected 60/60 as down, then 0/0 as pending, then 0/0 as unsuitable to purpose, then 0/0 with filter.
Spent too long trying to construct circuits for this request

Steps to reproduce:

Start Arti in proxy mode
Turn internet connection off and back on
Arti gets stuck in a loop trying to reconstruct a circuit until arti is manually restarted

What is the current bug behavior?
