fix(comms/tor): re-establish tor control port connection for any fail…

…ure (#4446)

Description
---
Retries tor control port connection for any error.

Motivation and Context
---
If any error is encountered with the tor control port connection, the connection is re-established.
Previously, this would only happen if the control port connection is cleanly closed

How Has This Been Tested?
---
Manually
