[lttng-dev] [PATCH lttng-tools master, 2.11] Fix: destroy command: put consumer output after destroy notifier

[Mathieu Desnoyers]

The destroy notifier needs to access the consumer output to format
the absolute path to the last chunk.

The observed problematic behavior can be observed by doing a
rotate and a destroy command in quick succession. Sometimes,
the resulting path printed by the destroy command is incomplete:

e.g. /archives/20190920T163616-0400-20190920T163618-0400-1

when we would expect:

/home/efficios/lttng-traces/auto-20190920-164425/archives/20190920T164437-0400-20190920T164439-0400-1
