[BUG] [Formatter] Extra blank lines inserted after blank_line_after_tag tags with preserve_blank_lines

[aarongoldenthal]

• I'm on the latest version of djLint
• I've searched the issues
• I've read the docs

System Info

• OS: Windows 10 21H2
• Python Version (python --version): 3.10.3
• djLint Version (djlint --version): 1.7.1
• template language: nunjucks

Issue

Using nunjucks templates with preserve_blank_lines: true, any tag listed in blank_line_after_tag has a new blank line inserted after it on every reformat.

The expected behavior in this case is that a blank line is inserted after the identified tags in blank_line_after_tag only if there is not already a blank line.

How To Reproduce

With config:

{
  "blank_line_after_tag": "extends",
  "preserve_blank_lines": true
}

and nunjucks file:

{% extends "layouts/base.njk" %}

<!-- other content -->

run djlint --reformat **/*.njk muliple times, and each time it adds a new blank after the extends tag.

This looks like it's related to #79.
