Mouse becomes unusable after quitting lazygit

[tmatz]

Describe the bug
After quitting lazygit, the mouse became unusable the next time I started vim.
The cursor does not move when I click the mouse.

This seems to be due to #1713 that I submitted earlier.
It seems that, terminal's mouse related state is not restored correctly.

I submitted an MR to gdamore/tcell here gdamore/tcell#512.

To Reproduce
Steps to reproduce the behavior:

1. start and quit lazygit
2. open some file with vim
3. enable mouse mode by set mouse=a
4. clicking the mouse always moves the cursor to the beginning of the center line.

Expected behavior
The cursor moves to the position where you click the mouse.

Desktop (please complete the following information):

• linux VM on Chomebook and Windows
• Lazygit Version 0.32.2
• f401164
