Remove WSC plugin from Demo preset

[Dumluregn]

As stated in the issue, plugin is actually still in presets, but excluded in config using removePlugins property.

However, currently the demo preset seems to be broken (or I can't use it 🤔 ) - after building the sample doesn't work, the plugins that the preset contains are odd and don't match anything. I'm not sure if I should fix this in this PR, or create a separate one.

Closes #54.

I got probably the same error:

Strange, there is no pastetools plugin even though it's a dependency of pastefromword one 🤔

I checked and even 4.14.1 demo doesn't work. The demo is used on our websites so either the workflow is different there or no one reported there is something wrong for a long time 🤔

Other difference is that, demo-build-config.js file is the one generated by our online builder and has additional preset: standard property but I'm not sure if it affects anything:

ckeditor4-presets/presets/demo-build-config.js

Line 29 in e15f2c6

preset: 'standard',

Anyway, I have reached @usqr to ask how exactly this preset is used and build.

So after talking to @usqr it turns out that demo preset is build like:

spawnSync( 'bash', [ 'build.sh', 'demo', 'all' ], { cwd: `${tempPath}/ckeditor4`, stdio: 'inherit' } );

which means the list of plugins doesn't make almost any difference. Still, using it like build.sh demo should work IMHO, since it's really confusing... The other thing is why pastetools is not added to the build even if it's a dependency of pastefromword which is there 🤔

Missclick... 😢

It's better to remove plugin from build config instead of using removePlugins. I fixed it in eb53ff9.

@Dumluregn could you extract it to a separate issue, having also #56 (comment), #56 (comment) and #56 (comment) in mind?

Rebased onto latest demo.
