toaster: comment out bldcontrol migration command

This fixes toaster startup failing after the preparatory patches
for bldcontrol application have been merged.

I slipped a bldcontrol-specific line into the toaster startup
script and this prevents toaster from starting. We comment
out this line until the bldcontrol application have been merged.

This patch adds the Project class models to the
toaster GUI data model. There is no specified use,
and the link in the Build class is optional.
