Add unit tests for analyzer (starting with handleJsDoc)

[tlouisse]

Hi,

When running the tool on our Lion components (LionInputAmount) in particular, we found out that handleJsDoc does not recognize object params built from multiple @param tags.

For instance:

class X extends HTMLElement {
  /**
   * @param {object} opts
   * @param {string} [opts.currency]
   */
  callMe({currency}) {
    return currency + '10.00';
  }
}

Is expected to return the following parameters:

     [
        {
          name: 'opts',
          type: {
            text: '{currency?: string}',
          },
        },
      ]

(currently it returns two params).

I created a failing unit test for the scenario above (it's skipped on purpose now, so this can be merged if wanted).

@thepassle since there were only integration tests for the analyzer package so far, feel free to say if you don't agree with the approach or want to do this in a different way :)

Did you also want to actually apply the function anywhere in this PR? Or are you planning that for a separate PR?

We can work around it atm, so I added .skip for now. But maybe in the future I want to do it in a separate PR :). @dakmor and me just had a look, and it should be possible to get all type info from the TS AST.

(Type info is found on the right)
