    Create proper regex if target is an UUID
    
    This patch only appends the version regex if:
     - the target doesn't start with "uuid:"
     - the target starts with "uuid:", but has another colon later on
     - the string after the colon consists of numbers
    
    The matching was changed to match numbers starting after the colon, not
    just somewhere after the column.
