fix: "Reply in direct message" should always appear if you have create-d permission

When PR RocketChat#36217 refactored useReplyInDMAction, it introduced a regression.
We previously checked for `!canCreateDM` (with a bang!) but that PR accidentally
negated it to `canCreateDM`.

Additionally, the conditional that includes `canCreateDM` was duplicated.
DRY it out.
