At some point a stray ';' got added into an autotest in a section
of code that is heavily copy pasted. So in turn nearly all the autotests
have this stray ';' after list_devices (and a few in other places).
These tests were failing (both with/without ofono) because iwd
was trying to autoconnect before the autotest had issued a
connect request (causing iwd to return a busy response). To fix
this, autoconnect was explicitly disabled in the config file.
