Focus in the local branches tab jumps after fetch

[wolfgangwalther]

Describe the bug

Whenever a "git fetch" operation runs/finishes the focus in the local branches seems to jump back to the branch it was on when starting the fetch.

This seems to happen for both manual fetches via "f" and auto fetches in the background.

To Reproduce
Steps to reproduce the behavior:

1. Change refresher.fetchInterval to 1 second.
2. Go to "Local branches"
3. Go through your list of branches maybe ~2 / second.
4. Notice that the selected branch jumps back repeatedly.

Expected behavior
A fetch operation should not affect the selected branch.

Additional context
This is especially problematic when you navigate to a different branch to delete it - if you do that fast enough and are unlucky enough... you'll end up deleting a different branch than you wanted to, because the selection jumps between "navigate to the branch" and "hit delete".
