[windows] split output on unix line endings

Looks like inquirer which is used by ui for creating prompts uses unix
line endings instead of enviornment specific. This causes the tests that
split the output to run assertions to fail.

Switched those specific tests to split on unix line endings as that split
the lines at the same place anyway and none of the regex are specific
enough to care about the extra `\r`
