Fix ostree admin kargs edit-in-place assertion when deployments

Browse Source 
are pending

This is to support pending deployments instead of rasing assertion.
For example:
```
$ sudo rpm-ostree kargs --append=foo=bar
$ sudo ostree admin kargs edit-in-place --append-if-missing=foobar
```
After reboot we get both `foo=bar foobar`.
