Bring back 2.5.0-dev version

This is something I missed during the review of PR 825 adding
the getDepositStatus function. The version should stay on 2.5.0-dev
as this is the -dev version automatically pushed to the NPM registry
and the last published non-dev version was 2.4.1. The next published
non-dev release should be 2.5.0.
