Phone: Ignore touch during network operators search

When network search is in progress, the progress dialog is
dismissed if user taps the screen. This in-turn cancels
manual search and switches to the previous screen.
This behavior can be avoided if the dialog property is set
to ignore user touch events.
If required BACK key can be used to cancel search and move
to previous screen.

PhoneApp: Initialize ToneGenerator when needed

Whenever there is a radio tech change, mSignalInfoToneGenerator
is released and never created. This leads to phone app crash later
when it is accessed for toneplay. This is fixed by creating the
instance (if null) before calling the APIs.
