get_realm is better in two key ways:
* It uses memcached to fetch the data from the cache and thus is faster.
* It does a case-insensitive query and thus is more safe.
This allows bot owners to configure which streams messages are delivered
to without needing to change webhook URLs or configuration files.

Testing directly against NarrowBuilder is convenient, as it
requires very minimal data setup to get a basic sanity check
of the SQL that gets generated.

Before saving a Message object, call update_calculated_fields()
to set the has_attachment/has_image/has_link fields.
Note that the pre_save hook we added here does not get called
if you call bulk_create, hence the explicit call to
update_calculated_fields() in do_send_messages().

If we call exclude_muting_conditions() with a non-stream
narrow, it will now include a condition to exclude streams
that are not in your home view. As of now, this code only
executes during testing, but it sets the stage for doing
better in:home queries on the back end.

If we are already narrowing to a stream, then we can disregard
muted topics in all the other streams and create a simpler query
for the DB to execute.

Due to the way we store muted topics, it is possible that a
muted topic stream name may no longer exist, and we need to
handle that case gracefully.

Previously, we assumed that num_before or num_after would be always be non-zero
after adjustment for the anchor. However, we don't adjust num_before or
num_after when a narrow is specified.
