Fix and enable MediaRulesTest:testMediaRule

[amartya4256]

Enabled some disabled tests which aren't in broken state anymore and fixed other disabled tests.
eclipse-platform/eclipse.platform#525

In the MediaRulesTest class, we test for if a CSS rule with @media tag is considered on parsing. Ideally we want the rule to be ignored.
Suppose we have a CSS string like:
@media screen, print {
BODY { background-color: red }
}
In the previous version of the test (which was disabled), it was expected that the rule "BODY { background-color: red }" under @media tag would be completely ignored. But now the behaviour has changed. It seems like the rules under @media are loaded indeed on parsing but the attributes are ignored, i.e. it looks like "BODY { }".

However, this behaviour doesn't have any side effect since a rule with no attributes neither change anything nor resets anything.

The failure of org.eclipse.ui.tests.progress.ProgressViewTests.testItemOrder might be unrelated to your changes (and it probably is). Please look for any existing issue on that (and, if there is none, please create one) and mention it here.

Better. You could add a use case that checks that the order doesn't play a role and extract a private method to improve readability

testSelectPseudo is failing. Please investigate and fix or undo changes in it
