import: avoid editor invocation when importing with "--exact" for exact-ness

Before this patch, external editor is invoked when imported patch has
no commit message, even if "--exact" is specified. Then, exact-ness is
broken, because empty commit message causes failure of committing.

This patch avoids editor invocation at importing with "--exact" for
exact-ness, because commit message in the patch should be kept as it
is in such case, even if it is empty.
