Test main thread mocked settings object but use that on the handler

Create a real object instead of mocking it instead.

When the device is very slow to run this test, cell might end
its lingering period in the middle of the test while wifi is
the default. VPN will then ignore it as an underlying network,
causing the test to fail.

      Added sleep in a strategic place to make sure the problem
      was correctly identified, and observed the test failing.
      After the fix, the test passes with the sleep.

The MTU from the socket is a much easier way to get the
correct MTU to any given destination. In particular this
is important for CLAT which used to be wrong :
on my device, with a perfectly working GoogleGuest :

Follow-up from commit Ie60829a65d0d9b5b63ad353695a820c0586e3665,
the interface field was cleared before returning the result to
the caller. However, this can cause problems in the
NetworkStats#subtract method. If the interface field is cleared,
the findIndexHinted method can match to a wrong entry.
This is because the keys of multiple entries will now be the
same. This can cause the subtract result to be unexpectedly
large and the return value of getUidStatsForTransport to be
mismatched with the values retrieved from other APIs.

But this change was not merged to U release branch and this change was
not well tested by dogfooding.

to use a common method that can slice NetworkStats by a given

This commit updates test to
- Execute IkeSessionCallback inside executor. The callback should
  be called from executor in production code but test trigger the
  callback from test main thread which will result in unexpected
  code interaction.
- Verify the timer directly. The origin design verifies
  interactions with Captor with uncertain interaction. Test
  should be able to verify the schedule() calls with the expected
  timeout value. Also, in lower performance device, device may
  still process previous interaction. Add longer timeout to reduce
  flakes.
