Lock lowdb file (#95)

* Lock lowdb file when using. Do not allow caching

* Linter fixes

* Move to non-jslib lowdbstorage to allow for lockfile

* update jslib

* Must ensure db file exists prior to initialization

proper-lockfile throws if the file its locking does not exist

* update jslib

* Let base handle file initialization
