Workaround for java.lang.IllegalArgumentException in android.util.ArrayMap

b/25613098 sometimes corrupt the bundle, resulting in a
IllegalArgumentException while validating.

Workaround with abandoning all the information in it.
The bypassed code only tries to extract data from the bundle, which can
already be null.
These are not critical for the dialer to function.
