IMS Bug Fixes

Note: This change was already in MNC-VT-DEV, but it somehow got lost when
things merged over to master.

1. Since IMS waiting call end indication can be received
   from lower layers, there is no need for call reject
   timer in case of IMS call. Also IMS calls need to
   distinguish between call reject and call ignore.
