Fix counting of current line-length

[lehni]

I noticed that the current line-length wasn't counted correctly depending on the setting of attributeSeparator.
This PR fixes that and adds tests for the various settings.

I really like the tokenNeedsSeparator member function, maybe we should extract it as a exported function to src/utils/common.ts. Then we could also write tests specifically for it 🤔

For an in depth review, I need more (free-)time 🙂

[lehni]

Thanks! The function relies on state on the PugPrinter class currently which is read from the options (this.neverUseAttributeSeparator and this.alwaysUseAttributeSeparator), so doing this would be a bit tricky! Also, I'm not sure we need to test the function in isolation, since we're already testing its effects through the many tests relating to attributeSeparator.

Sorry for the merge conflicts, cannot resolve them on my side 🙁
That will change when you later create branches in this repo directly 🙂

[lehni]

No worries! Will resolve later!

[lehni]

@Shinigami92 I've rebased the changes in this branch on top of master, resolving all the conflicts, and force-pushed a new version. I hope that's fine!

@lehni I hope I'm not to deep into "how I organize PRs", but is this feature merge ready?
If now more work is planned on your side, you should click the Ready for review Button and also the Re-request review Icon 🙂

@Shinigami92 when looking into the handling of literal attributes, I found a new bug in the current implementation of the plugin that happens as soon as you have both an id and class attribute on an element. I already have a fix for this in a follow up PR, but it will require #121 to be merged first. And I don't want to include it here, to not complicate this PR further.
