fix: table handles would crash

[YousefED]

Summary

When hovering between tables of different sizes (a larger table above a smaller one), this would crash in TableHandlesController because the table id and rowIndex / colIndex would be out of sync.

Closes #2355

Rationale

This is a quick fix to fix the crash, without a test. While looking into this, we encountered some related issues that can occur when using tables and collaboration. The table component needs a larger refactoring to accommodate for this which we'll add to the roadmap. As part of that refactor we'll also make sure this scenario will be covered in tests

Changes

Reset hovered table cell / row / col state when table changes

Impact

Testing

manual testing, see above for rationale
