We have an awful lot of integration tests and they are (comparatively)
really slow. Let's kill those that test edge case conditions and focus
on those that test that our functionality works as expected. Edge cases
can be better tested with unit tests.
Commit 4cae6a724e6d684eb157dd6d7328755694f228b2 introduced the message,
but it printed the wrong path, e.g. for `brew link sqlite`:
```
If you need to have this software first in your PATH instead consider running:
echo 'export PATH="/usr/local/opt/sqlite:$PATH"' >> ~/.zshrc/bin
```
where `/bin` is appended at the end, but should be inserted before
`:$PATH`: `echo 'export PATH="/usr/local/opt/sqlite/bin:$PATH"' >> ~/.zshrc`.
This patch fixes that and updates a test to verify it.
