Don't direct to market if no markets installed

Browse Source 
The search intent cannot be resolved if there aren't any
market apps installed, so it will cause Settings crashed by
the ActivityNotFound exception.

So we need to check if the market intent requst can be resolved.
Then determine to notify user to direct the accessibility services
to market to get TalkBack or not.
