fix hit box from the text of marker is incorrectly shifted to the right

[victorbrambati]

Type of PR: bugfix

PR checklist:

• Addresses an existing issue: fixes hoveredMarkerId for marker text within subscribeClick event #1270
• Includes tests
• N/A Documentation update

Overview of change:

• The function hitTestText() was using the Coordinate x from the item and not from own coordinate. So I created the item.text.x and put it in hitTestText().

Thank you @victorbrambati, I'll try review this today and add a test.
Was planning on creating a new version of the library today (v4.0.1) but might be worth waiting a bit longer so this can be included in that patch as well.
