What kind of change does this PR introduce?
Bugfix.

Did you add tests for your changes?
No, because this project doesn't have e2e tests to test such case.

Summary
This PR fixes the behavior of getLocalIdent, which cause bugs with webpack 4.
According to the chanelog, the rootContext was added. Loaders may use it to make stuff relative to the application root.

Also, loaderContext.options was removed, so the options.context is always value from loaderContext.context, which is actually filename without path.

So for example, if we have a/a.css and b/a.css both with .c {} content, the hash will be generated according to the a.css and c values (the same for these 2 independent files), which will cause class name conflicts.

Previous webpack versions don't include loaderContext.rootContext and as a result, this change is fully compatible with previous webpack versions and won't break anything.

Does this PR introduce a breaking change?
No

Can we solve this in one line?

I could refactor it to nested ternary expressions:
options.context = options.context || (loaderContext.rootContext ? loaderContext.rootContext : loaderContext.options && typeof loaderContext.options.context === "string" ? loaderContext.options.context : loaderContext.context)

@yavorsky it is better in future to maintenance, just add or remove new options/context and etc

But we could just remove condition case.
Nested ternary expressions are not allowed by current eslint config (and my conscience :) ).
