fix test for stashR localDB - was actually still an RDS db
give stashR objects a default name (they want one in addition to dir)
fix subsetting of stashR-backed neuronlists

* revealed now that test is working properly
* also reveal that they are very slow because each dbFetch re-reads the 
  db version info file (which is a plain text file with very long lines).
Merge branch 'feature/stashr'
