function FilterKernelTest::testUrlFilterContent

Tests URL filter on longer content.

Filters based on regular expressions should also be tested with a more complex content than just isolated test lines. The most common errors are:

• accidental '*' (greedy) match instead of '*?' (minimal) match.
• only matching first occurrence instead of all.
• newlines not matching '.*'.

This test covers:

• Document with multiple newlines and paragraphs (two newlines).
• Mix of several HTML tags, invalid non-HTML tags, tags to ignore and HTML comments.
• Empty HTML tags (BR, IMG).
• Mix of absolute and partial URLs, and email addresses in one content.
