[common_test] Unregister connection if killed
The symptom of this bug was that a (named) telnet connection which was
open and hanging during a timetrap timeout could no longer be opened
again in subsequent test cases.
Since the connection was hanging, ct_telnet:close/1 which was called
during end_per_testcase would fail (timeout) and cause common_test to
brutally kill the connection. The bug was that the connection was not
unregistered at this point. When trying to open the connection again
in the next testcase, common_test attempted to reuse the same
connection since it had not been unregistered. This failed since the
connection in fact was dead.
