Fixed update-url command not ran, Fixed wrong env contents

- Adds --force command to the update-url run so that it's actually ran
  during a restore. Option recently added on BookStack side to support.
- Updates env handling so that the old env contents are actually used as
  part of the merge. Updated existing test to cover.

Fixes #7, Fixes #8
