Test scenario for getContextSpecificModules() mocks only Skin->getTitle()
behavior, but while executing isAllowedPageAction() Skin will create a
UserPageHelper with default RequestContext. As RequestContext is not mocked,
$context->getTitle() will return undefined what could lead to tests crash
Changes:
- instead of mocking SkinMinerva::getTitle() pass test context with injected
title. Other tests will work properly as MediaWikiTestCase::tearDown() always
restes RequestContext to default
