libvirtconnection: Replace assert with AssertionError
The code wrongly assumed that assert always exists. When running in
optimized mode, the check would be skipped, and instead of getting an
AssertionError, which is the expected error for programmer error
(starting the eventloop twice), we could get a confusing
RuntimeException or RuntimeError from Thread.start (depending on Python
version).
RuntimeError misused in the standard library for all kinds of errors
that do not have builtin errors. It is particularry bad option when used
for usage error.
