[bisq-network/bisq] Improve handling when unable to connect to tor (#2399)

[Devin Bileck]

Issue: If an IOException is raised when attempting to create
tor and the hidden service, the application will just quit without
any indication to the user. One particular scenario where this occurs
is mentioned in https://github.com/bisq-network/bisq/issues/2398.

Cause: There is an explicit statement to exit the application when an
IOException is raised.

Fix: Rather than just exit the application, show an error message
and inform the user what went wrong.
