fix: issue accessing repo when not provided in query

Fixes #290

- [x] handle trying to access repository from dictionary when not present (use default of empty string)
- [x] add test to ensure we cover this scenario
- [x] handle issue where `time_to_close` variable was being access before possibly being declared
