Change subject: textlib.extract_templates_and_params tests
......................................................................
textlib.extract_templates_and_params tests
allow textlib.extract_templates_and_params_mwpfh to be
accessed and tested even if config.mwparserfromhell is disabled.
Delay import of mwparserfromhell until it is actually used.
Merge common test results for mwpfh and regex, highlighting the
case known to be different, and mention them in the docstring.

+ This uses the package L{mwparserfromhell} (mwpfh) if it is installed

+
+ There are minor differences between the two implementations.
+
+ The two implementations return nested templates in a different order.
+ i.e. for {{a|b={{c}}}}, mwpfh returns [a, c], whereas regex returns [c, a].
+
+ mwpfh preserves whitespace in parameter names and values. regex excludes
+ anything between <!-- --> before parsing the text.
