fast-import: fix erroneous handling of get-mark with empty orphan commits
When get-mark was introduced in commit 28c7b1f7b7b7 ("fast-import: add a get-mark command", 2015-07-01), it followed the precedent of the cat-blob command to be allowed on any line other than in the middle of a data directive; see commit 777f80d7429b ("fast-import: Allow cat-blob requests at arbitrary points in stream", 2010-11-28). It was useful to allow cat-blob directives in the middle of a commit to get more data that would be used in writing the current commit object. get-mark is not similarly useful since fast-import can already use either object id or mark. Further, trying to allow this command anywhere caused parsing bugs. Fix the parsing problems by only allowing get-mark commands to appear when other commands have completed.
