If a change gets submitted, the remaining open changes get reindexed
asynchronously to update their mergeability information. If the test
does further mergeability assertions before the asynchronous reindex
completed they fail because the mergeability information in the index
was not updated yet. To avoid this flakiness we index the open change
synchronously now, before the further mergeability assertions are done.
