Mismatched italics syntax causes template filter to fail sometimes

[mzmcbride]

When there's mismatched italics syntax, the .filter_templates() method fails to properly parse the page sometimes.

Sample script:

#! /usr/bin/env python

import mwparserfromhell

def parse_text(case_text):
    parsed_page_text = mwparserfromhell.parse(case_text)
    print(len(parsed_page_text.filter_templates()))
    for template in parsed_page_text.filter_templates():
        print(template.name.strip())

case_text = """\
{{Infobox SCOTUS case
  |FullName=''[[et vir]]'
}}

'''''Hello there'''''
"""

parse_text(case_text)

case_text = """\
{{Infobox SCOTUS case
  |FullName=''[[et vir]]''
}}

'''''Hello there'''''
"""

parse_text(case_text)

case_text = """\
{{Infobox SCOTUS case
  |FullName=''[[et vir]]'
}}
"""

parse_text(case_text)

Of note: |FullName=''[[et vir]]' is mismatched in the first case and the third case.

Current buggy output:

0
1
Infobox SCOTUS case
1
Infobox SCOTUS case

Expected output:

1
Infobox SCOTUS case
1
Infobox SCOTUS case
1
Infobox SCOTUS case

Duplicate of #40. Use mwparserfromhell.parse() with skip_style_tags=True as a workaround.
