shill: cellular: Handle vanish of bearer when getting its properties.

This CL changes CellularCapabilityUniversal::OnListBearersReply() to get
the properties of a bearer via a single invocation of
DBusPropertiesProxy::GetAll() instead of multiple invocations of
different property getters in mm1::BearerProxy. This allows us to handle
the vanish of a bearer more gracefully when getting its properties over
DBus.

BUG=chromium:244496
TEST=Tested the following:
1. Build and run unit tests.
2. Run network_3GSmokeTest test on platforms with Y3400 and E362 modem.
3. Run network_3GModemControl test with pseudomodem.
4. Test a few 3G dongles that use PPP.
