Revert regression introduced in ngeo displayWindow component

[adube]

This patch fixes an other regression introduced by the automatic changes in: 6d38eed

This time it's the ngeo displayWindowComponent.

Explanation

An angular component gets its its binding properties (i.e. those defined in the html) being set their values in the $onInit method. In the constructor, their values are not yet set but we do need to type them:

   /**
     * @type {boolean}
     */
    this.resizable;

The issue introduced by the auto-patch is that they got values assigned according to their type:

    /**
     * @type {boolean}
     */
    this.resizable = false;

This breaks the setting of the value by Angular in $onInit. Therefore, we should not do that. It's okay to leave the type as boolean, because the property itself in this will be set to a boolean in $onInit. The angular option (through the biding) is optional but that doesn't matter.

There may be more regressions like this.
