== Motivation
Mute a log channel, for which the Logger object is injected by
service wiring, for a service that is overridden by default,
such as 'DBLoadBalancerFactory'. For that, calling setLogger()
mid-test would be too late.
== Changes
* Add a test-only method to LegacyLogger that makes it possible
to change its `minimumLevel` attribute, thus making it turn
itself into a NullLogger if raised to infinity. This is the
same principle we use already for disabled log channels when
using MediaWiki normally (see LegacyLogger::__construct).
* Previously, the developer's LocalSettings.php was loaded
which includes the Spi configuration. This meant other Spi's
could be configured which means we might not be dealing with
a LegacyLogger object.
Similar to what we do with ObjectCache and JobQueue already,
make the default Spi in tests the same as the normal MW default.
* Add setNullLogger() which makes use of these two.

Basically turning Mediawiki to MediaWiki as all other classes exist
in that namespace

When a unit test fails it is possible, perhaps even likely in some
cases, that some code that was run logged useful information about
how that failure came to be.
Help people out, tell them what happened!
