largefiles: add tests for summary/outgoing improved in subsequent patches

This patch adds tests for summary/outgoing improved in subsequent
patches, to reduce amount of diffs in each patches.

This patch adds new revisions below:

  - revision #2 adds new largefiles, but they contain as same data as
    one already existing

    this causes that multiple standins refer the same data entity

  - revision #3, #4 and #5 change the already existing largefile

    this causes that multiple data entities are outgoing for the standin.
    #5 can be used to check de-duplication of "(hash, filename)" pair.
