zerver/lib/actions: removed do_set_realm_* functions and added
do_set_realm_property, which takes in a realm object and the name and
value of an attribute to update on that realm.
zerver/tests/test_events.py: refactored realm tests with
do_set_realm_property.
Kept the do_set_realm_authentication_methods and
do_set_realm_message_editing functions because their function
signatures are different.
Addresses part of issue #3854.
Changing assert_in_success_response to require List[Text] instead of
Iterable[Text] prevents the following misuse:
self.assert_in_response_success("message", response)
Currently, this will check whether 'm', 'e', 's', 'a', and 'g' separately
appear in the response, which is probably not the intended behavior. The
correct usage is as follows:
self.assert_in_response_success(["message"], response)
This adds to Zulip support for a user changing their own email
address.
It's backed by a huge amount of work by Steve Howell on making email
changes actually work from a UI perspective.
Fixes#734.
