1. Fix misleading exception in has_entry …

   If `has_entry` is called without any arguments, it will raise an
   exception like the following:
   
   ```
   ArgumentError: Too many arguments; use either a single argument (must be a Hash) or two arguments (a key and a value).
   ```
   
   This is because we don't check if the `options.length` is zero so when
   it is, the `else` branch executes and prints the above error. We can fix
   this by simply adding another branch to cover the case when
   `options.length` is zero.
