Restore "tests: Disable unstable unit test."

This restores commit 5c8a224e2d, which
disabled the unstable testReloadWhileDisconnecting testcase. Later this
was reverted by commit 4fc7bc76db, but
nothing was really done to improve the stability, so go back to disabled
for now. (Till somebody has time to debug & fix the root cause here.)
