sync: merge project updates with status bar

The current sync output displays "Fetching project" and "Checking out
project" messages and progress bar updates independently leading to a
lot of spam.  Lets merge these periodic outputs with the status bar to
get a little bit tighter output in the normal case.  This doesn't solve
all our problems, but gets us closer.
