templater: remove workaround for escaped quoted string in quoted template

This patch backs out 554d6fcc3c84 which should no longer be needed.

The test for '{\"invalid\"}' is removed because the parser is permissive for
\"...\" literal.

    # template, but we are likely to escape <"> in quoted string and it was
    # accepted before, thanks to issue4290. <\\"> is unmodified because it
    # is ambiguous and it was processed as such before 2.8.1.
