Description

Events are not traced if we enable a disabled channel after UST application has been started.

How to reproduce:

#console 1
lttng-sessiond -d
lttng create; lttng enable-event -u -a; lttng start
lttng disable-channel -u channel0

#console 2
./hello 10

#console 1 -- before end of 10 seconds
lttng enable-channel -u channel0

#wait until hello completes
#console 1
lttng stop
lttng view

Expected result: all hello events are traced.
Actual result: 0 event traced.
