Fix/load extension log load failure (#641)

* Log extension load failure

In case the extension couldn't be loaded the error was never logged, making it impossible to analyse what was going on

* Log exception in "GetCatalogueSource:: getCatalogueSourceOrNull"

In case "GetCatalogueSource::getCatalogueSource" threw an error, this was never logged here
