The keystone charm sets db-initialised to true after initializing the
database the first time. However, if the database application is
removed, this flag is not unset.
This results in breakage on attempts to re-add a shared-db relation
with a new database application, as the charm will not attempt to
re-initialize the database prior to doing DB operations.
This fix simply ensures that we unset this flag prior to finalizing
removal of the shared-db relation.
