WIP - fix SMS quick reply for MultiSim devices.

Quick Reply will default to SIM slot 0 for MSIM devices, even if it is
not an active SIM. This will cause a loop of fail that tries to send the
message over and over.

So, actually use the default _active_ sim slot here.

TODO:
  - Determine the sim slot where the message was delivered and use that
    one first, if active.
  - Fail more gracefully with an error message, if the message cannot be
    sent.
