Not receiving GP_EVENT_CAPTURE_COMPLETE event when capturetarget = Memory Card

[artyom-beilis]

Describe the bug

When using trigger capture and waiting for events I receive FILE_ADDED but never receive GP_EVENT_CAPTURE_COMPLETE event when capturetarget = Memory Card, When capturetarget is set to internal memory I receive capture completed.

Note, I can't use only FILE Added since I don't know in advance how many are saved (jpeg, raw or jpeg & raw)

Name the camera
Canon EOS 7D

To Reproduce

Since I use libgphoto2 basic sequence is just set save target to sd card and than catpture completed event is not fired.

I'm attaching libgphoto log (with some additions) for case when target is sdcard and internal memory

With internal memory there is an entry camera_wait_for_event:entry type 0004 it does not appear when target in SDCard.

Same with latest libgphoto2 2.5.30.1

Currently, I workaround it by requiring from user to save only a single type of file per trigger - either raw or jpeg but not both. So I can take action on "file added" event.

So now I implemented same requirement, limitation as Indi. But I'd rather prefer to use capture complete event as more correct and flexible one.
