Fix @storybook/client-logger import

[eur00t]

Issue:
@storybook/client-logger was imported incorrectly in @storybook/addon-info, which results in runtime error TypeError: Cannot read property 'warn' of undefined

What I did

Replaced default import with named import.

How to test

1. Use marksyConf in storybook configuration.
2. When running storybook in the browser, proper warning message should be shown instead of the runtime error.

Is this testable with jest or storyshots? No

Does this need a new example in the kitchen sink apps? No

Does this need an update to the documentation? No

If your answer is yes to any of these, please make sure to include it in your PR.

Nice catch @eur00t! I wonder why eslint didn’t catch it though

Upd: it turned out that we just don't use the corresponding imports/default rule. I'll add that (and probably some others)

[eur00t]

@Hypnosphi thanks! I think it'll be helpful to add import/default and import/named eslint rules from eslint-plugin-import (I can see that currently we use import/no-unresolved only).
With import/default there can be problems though, because some packages doesn't export ES6 modules, for example @storybook/client-logger. It might work when "jsnext:main" is defined.
