Previously, if we provided getty@.service to systemctl edit it would
have failed when using the bus because it is an invalid unit name.
But it would have succeeded when searching in the filesystem.

Now, we check if we have a template, if we do we search in the
filesystem, if we don't have a templae and we can use the bus, we do.

Furthermore, if we provided getty@tty1.service it would not have worked
when searching the filesystem, but it would have worked with the bus.
So now, when using the filesystem we use the template name and not the
unit name, and the same when logging errors.

journal: map objects to context set by caller, not by actual object type

When the caller of journal_file_move_to_object() specifies type==0,
the object header is at first mapped in context 0. Then after the header
is checked, the whole object is mapped in a context determined by
the actual object type (which is not even range-checked using
type_to_context()). This looks wrong. It should map in the
caller-specified context.

An old comment in sd_journal_enumerate_unique() supports this view:
    /* We do not use the type context here, but 0 instead,
     * so that we can look at this data object at the same
     * time as one on another file */
Clearly the expectation was that the data object will remain mapped
in context 0 without being pushed away by mapping other objects in
context OBJECT_DATA.

I suspect that this was the real bug that got fixed by ae97089d49
"journal: fix access to munmapped memory in sd_journal_enumerate_unique".
In other words, journal_file_object_keep/release are superfluous after
applying this patch.
