project: fix m/ generation when switching manifest branches

Browse Source 
We were updating the per-checkout m/ pseudo ref when syncing, but we
only created the common m/ redirect when initializing a project for
the first time.  This is fine unless the user switches the manifest
branch in an existing project, then we never create that redirect.
