Fix and re-enable EvictionWithoutReplicasReachesLWM for magma

    // The test makes assumptions on the memory state of the system at storing

    // items. In particular, we load some items until we hit the HWM for

    // preparing for HT ejection.

    // Now that we introduce a limit on checkpoint mem-usage (MB-47386), when

    // loading data we need to simulate checkpoint mem-recovery, or we would

    // never reach the HWM otherwise as we'll hit the checkpoint quota first.

    // All fine so far, under couchstore all behaves as expected.

    // Problem under magma is that it allocates a good chunk of the bucket quota

    // when we persist for allowing chekpoint-mem-recovery. We hit the HWM by

    // magma allocations that seem to be intermittently freed (maybe in magma

    // threads?) as soon as we return from the load-data function. Thus pushing

    // the system back below the HWM and invalidating the test pre-requirements.

    // At the time of writing magma is also facing some major internal memory

    // usage and tracking issues.

    // For all that, I'm disabling the test for magma for now.

    // @todo: fix and re-enable, tracked in MB-47481
