Multiple fixes for class attribute conversions

[MrHaila]

Closes #508

This PR adds tests and fixes for previously untested variations of class literals in increasingly complex scenarios. Most of them output non-valid Pug code currently.

I fixed all the new test cases to output valid Pug code without regressions, so this is probably safe to merge. I don't have full confidence that there are no other (currently untested) bad combinations of the various options, but this is for sure better than before.

Examples of code that previously outputted invalid Pug but now work:

// Class literals at the end of attributes did not work.
div(attribute="value").foo
div(class="bar", attribute="value").foo
div(attribute="value", class="bar").foo.baz
div(
  attribute="value"
  class="bar"
).foo.baz
div.foo(attribute="value" class="bar").baz

// Class literals ending at : did not work
div(class="foo").bar: span Text
div: span.foo
div: span(class="foo")
div.foo: span.bar(class="baz").foo

// Class literals in an interpolated line did not work
div.foo(class="bar").baz: h1.foo(class="bar").baz Let's really #[span.foo(class="bar").baz get nasty]!

Back from vacation, I'll have a look the next few days, because I need to ensure that everything is correct

[Shinigami92]

Added 1-level indentation tests and made use of checkTokenType

I just saw that for some cases we have still a div leftover like with L17
But either this might get formatted by just a second run, or it can be fixed by a later MR (if it is even a problem)
