templater: strip single backslash before quotation mark in quoted template

db7463aa080f fixed the issue of double escapes, but it made the following
template fail with syntax error because of <\">. Strictly speaking, <\">
appears to be invalid in non-string part, but we are likely to escape <">
if surrounded by quotes, and we are used to write such templates by trial
and error.

  [templates]
  sl = "{tags % \"{ifeq(tag,'tip','',label('log.tag', ' {tag}'))}\"}"

So, for backward compatibility between 2.8.1 and 3.4, a single backslash
before quotation mark is stripped only in quoted template. We don't care
for <\"> in string literal in quoted template, which never worked as expected
before.

  template  result
  --------- ------------------------
  {\"\"}    parse error
  "{""}"    {""} -> <>
  "{\"\"}"  {""} -> <>
  {"\""}    {"\""} -> <">
  '{"\""}'  {"\""} -> <">
  "{"\""}"  parse error (don't care)

This test file aims at test topological iteration and the various configuration it can has.

  $ cat >> $HGRCPATH << EOF
  > [ui]
  > logtemplate={rev}\n
  > EOF

On this simple example, all topological branch are displayed in turn until we
can finally display 0. this implies skipping from 8 to 3 and coming back to 7
later.
