Code review comment for lp:~gary/juju-gui/simplifycharmstore

Thank you for the review, Ben. I have comments in-line, largely in line
with what we discussed in person.

You gave me permission to go ahead and land this. Kapil mentioned that
he questioned the use of the Model load/sync code given that it is of
minimal value to our use case, but if I need to address this I will do
it in a subsequent branch.

Thanks

Gary
