This test uses Measurement.create_tor_config to
create a configuration string for tor when the BASETORRC env variable is set.
It first sets the environment variable, then initializes an empty
measurement and then calls create_tor_config with a series of well known
variables. The resulting config is tested against the expected config for
both client and server. Also
this tests if the contents of the env variable are correctly recorded in
the class attribute base_config.
The environment variable is unset only if the test is successful.
