At numerous places in the code, something like this is performed:
String name = Downtime::AddDowntime(...);
Downtime::Ptr downtime = Downtime::GetByName(name);
However, `downtime` can be a `nullptr` after this as it is possible that
the downtime is deleted in between.
This commit changes the return type of `Downtime::AddDowntime` to return
a Downtime::Ptr instead of the full name of the downtime. `AddDowntime`
performs the very same `GetByName()` operation internally, but handles
the `nullptr` case correctly and throws an exception.
