EchoTitleLocalCache title cache resolution ends up querying the database
to resolve title id to Title object.
In some corner case, we might only have one page in the database (UTPage
as provided by MediaWikiTestCase), thus the id 2 would not resolve to a
Title breaking the test.
Use insertPage() to ensure we have a second page.

Currently echo attempts to find a signature by looking for a series of
strings starting with what it thinks are the current aliases of NS_USER
and NS_USER_TALK. This has shown to be error prone, see the linked bug
for how a change to ru.wikipedia.org/wiki/Mediawiki:Signature broke
mention notifications.
Patch switches things arround to pull wikilinks out of the text and run
them through the Title class. The results of this parsing are checked
for NS_USER and NS_USER_TALK, giving a much stronger guarantee of finding
translated namespaces.
