1. No longer throw SecurityException when we fail to resolve the intent.
Return false instead.
2. Throw IllegalArgumentException early if the incoming intent is not
explicit.
3. Throw SecurityException with different error message. It makes debug
easier and allows tests to verify a particular thing happened.
