Crash on deleting a branch in combination with filtering

[Krismix1]

Describe the bug
Lazygit crashed with "invalid memory address or nil pointer dereference error" after deleting a branch and applying filtering.
It seems this was previously fixed in #3058, but it appeared again (I tested on commit 36918560, and it worked fine there).

To Reproduce
Steps to reproduce the behavior:

1. Create a branch named "dummy"
2. Focus branch list view
3. Press /
4. Type: dummy
5. Press Enter, d, Enter

Expected behavior
I expected lazygit to continue and either redo the filter operation, or show all branches.
