[Console] fixes tests

Previous `StringInputTest::testInputOptionWithGivenString` test was broken.
Trying make it pass broke the way `StringInput` is used in the console.

Two things to know abour the `StringInput` class in its actual state:
*  the second argument in the constructor is useless
*  the `bind` method **must** be called in order to access arguments/options
