Change between branches generate commits
## Description
When I change between branches, Kactus generate a commit with a lot of file changes. This commit disappears if you let Kactus loading more time, but will be fantastic If this commit doesn't appear.

I understand that this is happening because there is a gap when Github change files between branches and when you are in the "new" branch you still have files from another branch. 

## Version
* Kactus: 0.3.25
* Operating system: Mac OS X Catalina 10.15

## Steps to Reproduce
1. Change to another already created branch
2. Look in commit panel

### Expected Behavior
Change to another branch without seeing this commits

### Actual Behavior
A lot of new commits appears
