[BUG] Close after uninstall not working with homebrew

### Describe the bug:
When the option "Close after uninstall" is set as well as "Homebrew cleanup after uninstall" pearcleaner does not close automatically.

I am not sure if this is intended behavior or a bug.

### Expected behavior:
Have Pearcleaner close.


### Info:
 - OS: [15.4]
 - Pearcleaner Version: [4.4.4]
