zulip/zerver/tests/test_realm_linkifiers.py
Zixuan James Li 011b4c1f7a populate_db: Populate linkifiers. 
The curl examples of reordering linkifiers require there to be some
linkifiers in the database to be reordered. This adjusts some test cases
so they do not assume that there is no linkifier in the test db.
