core: Delete AbstractTransportTest.clientShutdownBeforeStartRunnable

The test was added in e4e7f3a06 when InProcess stopped returning a
Runnable from start(). In c5a63a1 we realized (indirectly) that there's
no point in using the Runnable any more.

This test failed with Binder (which seems to have been using the
Runnable unnecessarily), and InProcess, Netty, and OkHttp don't use the
Runnable. Instead of fixing it, we'll just move toward stopping using
Runnable.

I'm not removing the Runnable usage from Binder in this commit because
this test is currently causing CI failures and I don't want to do a
behavior change when fixing it.
