Fix lxml deprecation warning tests.

The class BeautifulStoneSoup is instanciated first in
bs4.tests.test_soup:LXMLTreeBuilderSmokeTest.test_beautifulstonesoup_is_xml_parser
causing the UserWarning to be printed once. However, the deprecation test will
fail afterwards:

ERROR: test_beautifulstonesoup (bs4.tests.test_soup.TestDeprecatedConstructorArguments)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/root/Projects/python/beautifulsoup/bs4/tests/test_soup.py", line 69, in test_beautifulstonesoup
    self.assertTrue("BeautifulStoneSoup class is deprecated" in str(w[0].message))
IndexError: list index out of range

Instead, don't eat the UserWarning in the first test so that the second one can
catch it properly.

Don't provide encoding for XML unicode tests with LXML.

ERROR: test_can_parse_unicode_document (bs4.tests.test_lxml.LXMLXMLTreeBuilderSmokeTest)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/root/Projects/python/beautifulsoup/bs4/testing.py", line 498, in test_can_parse_unicode_document
    self.assertEqual(u'Sacr\xe9 bleu!', soup.root.string)
AttributeError: 'NoneType' object has no attribute 'string'

As described at http://lxml.de/parsing.html#python-unicode-strings LXML doesn't like
Unicode XML that specifies a (wrong) encoding.
