Fix: ui_context: crm configure up prompt #1466 (#1481)

The regression was introduced in beb26f3
Before beb26f3 it was like
```
crm(live/15sp5-1)configure# primitive d Dummy
crm(live/15sp5-1)configure# up
There are changes pending. Do you want to commit them (y/n)?
```
After beb26f3 there is no prompt `There are changes pending. Do you
want to commit them (y/n)?`
This change brings the prompt back.
