Verify isEmpty by checking if one row exists
In case of large MediaProvider database we may see ANR due to query
timing out while counting for number of rows. To avoid this, changed
isEmpty() to use LIMIT clause to query and return just one row to
confirm that table is empty instead of traversing the whole database for
count(_id).
