makefile: Fix 'samba-git-update' target

This target is meant to be used before ./configure
so most probably there won't be config.mk available.
Hence, skip it.

mapistore: Bypass Embedded message creation for Tasks in Outlook

Right now SOGo back end doesn't support embedded messages in
a Task, which leads to a nasty runtime Obj-C exception.
This effectively kills openchange process, so it is better
we just return MAPI_E_NOT_IMPLEMENTED for such objects and continue
to work instead of breaking badly.

This is a temporary fix for: issues => 7345
