fix for Issue #29 : Already Registered users shoulb checked first then
values should be set to objects.

before fetching from parameter , fetching only Email id and checking in
databse for same id if any entry found in database , giving user the
proper information of already registered , and if email id not dfound in
databse , then started fetching all other form data and saving it into
databse fo9r signup process.
