Refactor Rename in imported files doesn't work.

[OlgaYurchuk]

There is two yang files: opendaylight-flow-statistics.yang and open-statistics-types.yang
open-statistics-types.yang is imported to opendaylight-flow-statistics.yang

There is the grouping name "aggregate-flow-statistics" in both files.
I choose this grouping name in opendaylight-flow-statistics.yang
Refactor->Rename
I change grouping name from aggregate-flow-statistics to aggregate-flow-statistics-test and open preview

Expected behavior. File open-statistics-types.yang is in "Changes to be perfomed"
Actual behavior: File open-statistics-types.yang is not in "Changes to be perfomed"

Very hard to reproduce.
First I tried it in my workspace, which is in sync with master. I succeded to reproduce. Then tried it again. It worked fine. Then again an again. Nothing helped.
Then I rolled back sources of both repos to commits of 1 Oct. It neither helped.
Finally, I created a new installation of eclipse, installed the required plugins. No hope: I've always got an attempt to change 2 files instead of 1.
