Public bug reported:

We recently removed the numcolumns column from views as it is obsolete

But we get an error when upgrading from older versions of Mahara, eg
15.04 as the upgrade script wants to create a new view before the
numcolumns column is removed form db but doesn't have a default value
for it in lib/view.php

For example, we get this error:

Failed to get a recordset: postgres8 error: [-1: ERROR: null value in
column "numcolumns" violates not-null constraint]

>From calling the function install_system_portfolio_view() at
htdocs/lib/db/upgrade.php line 4182

I'll add back in the default value for numcolumns into the lib/view.php
file so that things will save correctly before the column is removed
from db during upgrade.
