Improve test suite robustness vs transient network errors
The amount of false positives we get from tests failing due to transient network errors (e.g. Tor being slow, Exit node blocking, the live destination servers having issues etc.) is already problematic, and is blocking deployment in our Jenkins infrastructure (#8539 (closed)). Let’s make the tests must susceptible to these issues simulate a user retrying (in a suitable manner) whenever such errors occur.
