Fix bug with date and date time widgets where you cannot reenter without moving away

[jingtang10]

User experience :

1. Open the date widget
2. Select date
3. Press ok
4. Try to open the date widget again. It Does not open
   If some one makes a mistake entering the date/time, the have to enter the time/date and then only then are they able to reopen the date widget. Not sure why this is happening.

Also Looks like TextInputLayout remains highlighted if you click on a radio button / check box.
