gitui should return to the same screen after a stash has been popped

**Is your feature request related to a problem? Please describe.**
When a stash record has been popped gitui goes to the Status tab instead of remaining in the Stashes tab.

**Describe the solution you'd like**
remain in the Stashes tab.

**Describe alternatives you've considered**
n/a

**Additional context**
It's illogical to switch to another tab at this point because the user is likely to pop another stash record at this point.
