Tanguy Leroux 73ddc2323b [Test] Relax LocalExporterTests on node_stats checks
The test is too rigid on checking the right number of node_stats documented that are collected. It happens if a node takes time to start, the node_stats count % numNodes will always be different than 0.

It also adds more logging for LocalBulk failures.
