Our coding guidelines say to not use `test` with `-a` and `-o` because
it can easily lead to bugs. Convert trivial cases where we still use
these to instead instead concatenate multiple invocations of `test` via
`&&` and `||`, respectively.
While not all of the converted instances can cause ambiguity, it is
worth getting rid of all of them regardless:
- It becomes easier to reason about the code as we do not have to
argue why one use of `-a`/`-o` is okay while another one isn't.
- We don't encourage people to use these expressions.
