Tor does not connect/bootstrap with Bridge and no microdescriptors

Summary

With UseMicrodescriptors set to 0, it is not possible to connect to the network over Bridge. The connecting process is stuck at: Bootstrapped 75% (enough_dirinfo): Loaded enough directory info to build circuits

Steps to reproduce:

1. Configure any Bridge running new versions of Tor and set UseMicrodescriptors 0
2. Try to connect to the network

What is the current bug behavior?

What is the expected behavior?

Tor connects to the network

Environment

Version: 0.4.7.8 OS: Linux, self-compiled. Also tried on Fedora 35 with 0.4.6.9.
