Details:

=Description=

Octave fails to recognize that some functions from octave forge packages are
already implemented. It returns a warning message stating that the function
was not implemented when actually it has been implemented.

=How to reproduce= 


pkg list
Package Name  | Version | Installation directory
--------------+---------+-----------------------
     control *|   3.1.0 | /home/edumapurunga/octave/control-3.1.0
          io *|  2.4.12 | /home/edumapurunga/octave/io-2.4.12
      signal *|   1.4.0 | /home/edumapurunga/octave/signal-1.4.0
  statistics *|   1.4.0 | /home/edumapurunga/octave/statistics-1.4.0
    symbolic *|   2.7.1 | /home/edumapurunga/octave/symbolic-2.7.1

G = tf(1, 1)
warning: the 'tf' function belongs to the control package from Octave Forge
but
has not yet been implemented.

Please read <https://www.octave.org/missing.html> to learn how you can
contribute missing functionality.
error: 'tf' undefined near line 1 column 5


It also happens to other common functions from control and signal packages.

=Partial Solution=

If I reinstall those packages then it works again. However, when I restart
Octave the same issue is reported.
