commandline_frame.ts: Fix exception thrown because of 'tri' not existing

Browse source 
The commandline_frame document does not have a window.tri object. This
makes the commandline throw an exception on page load. We fix this by
using 'window.tri || {}' in order to avoid to avoid issues should
'window.tri' be defined in the command line one day.
