fix: remove unnecessary whitespace when handling classes

[jakovljevic-mladen]

Overview

This PR fixes an extra space being added to the element's class attribute. For example, in my app, I usually have an extra space:

What is it?

• Feature / enhancement
• Bugfix
• Docs / tests / types / typos

Description

This PR has two commits:

• the first commit adds a lot of tests for serializeClass and serializeClassWithHost functions;
• the second commit fixes an issue described in the image above.

The first commit will fail test serializeClassWithHost -> should serialize context with empty $scopeIds$ without a fix from a second commit because expected value is 'bar bar-baz baz-bar', but actual value was ' bar bar-baz baz-bar'. It is fixed with the second commit and the expected values matches actual value.

This is minor and an extra space in the string won't harm anything, but it was still an easy fix.

I can't make my local e2e test run properly. I'm getting errors like:

Cannot find module '/.../qwik/packages/qwik/dist/optimizer.mjs'
imported from /.../qwik/starters/dev-server.ts

I found that CI executes these lines, but they don't work for me (errors with no matches found: builderio-qwik-distribution/*).

What can I do? How can I create/populate /qwik/dist folder?

You can run pnpm build and you will create dist folders

Thanks @gioboa. I managed to run e2e test locally, but it seems that these tests are failing on main branch as well 🙈

[gioboa]

I'll try in my local environment and I will let you know

--- UPDATE ---

I re-run all the checks and it ok now

[gioboa]

Thanks @jakovljevic-mladen it looks great to me.
