MongoDB driver does not take claim grace into account on update

[Kurt Griffiths]

When a claim is updated, the associated messages have their lifetimes extended and their TTL updated without taking into account the claim's grace period as is done in the create method of ClaimController.

In fixing this, we should consider finding a way to DRY up these two methods to avoid this sort of bug in the future!

    Fix ttl and grace story for claims updates

    Claim's updates are currently extending the life of a claim by extending
    its `ttl` without taking into account the claim's grace. In addition to
    this, the `ttl`'s default value is 60 for claim's renewal instead of
    being the value of the configured default ttl.

    This patch allows users to specify a `grace` when renewing a claim. If
    `grace` is not present, it'll use the configured default value for it.

    The change doesn't break backwards compatibility as in v1_0 a ttl *is*
    required for claims renewal.

    Closes-bug: #1356184
