oldtests: Run old tests in :terminal

Reasoning:

- No need to check for terminal size.
- No need to mess with terminal title.
- Allows old tests to timeout with the rest of the build proceeding.
- Less and less messy output to travis log.
- Opens a path allowing old tests run in parallel. Though last bit needs test
  refactoring.
