Fix crashes when attempting to navigate empty chart lists. #14

Closed RealistikDash closed 1 year ago

This PR fixes crashes regarding navigation attempts through an empty chart list.

Pressing any arrow key while inside an empty charts list would result in a division by zero error (for up and down arrows) or an index error (for the right arrow).

This PR adds a check that checks for an empty chart in the input handler.
