vt71: Import does not de-activate fields according to presence configuration

Import does not de-activate fields according to presence configuration in vtiger_field table.

Steps:

1. Go to Ticket => All => Import => Step 2

In code the column is compared as number but the field is loaded as string. So far i have not found the cause of the type as string since the database field is defined as int.

A quick fix could be comparing the value as a string but it does not feel like the right solution.

   if($fieldInstance->getPresence() === '1') {
     continue;
   }
