[SailfishDevel] Getting odd error when attempting to use LocalStorage.changeVersion

Hi all,

features necessitates a storage schema change.  So I wrote a utility
function that tries to open a connection with the correct version, and
falls back to calling db.changeVersion if there is a version mismatch.
