@edsiper
input: fix wrong thread(s) deletion (fix #135)
affd2e6 
The current input plugins when running in a co-routine, was doing a
wrong thread deletion, instead of delete the thread associated with
a specific ID, it was deleting 'all threads contexts', leading to
a segfault when using in_health plugin.

This patch let the input thread deletion just focus on the thread
associated to the given id.
