Commit for ref only - Add tests for pinning / unpinning

This would be my preferred way to add tests for pinning and unpinning.
My very first attempts resulted in python errors when running under
Vader and seemingly it was unpinning that was causing the problem.
Adding sleep commands in allieviated the issues, but as it is now these
tests will still fail. The result will be:

A note to pin
unpinned

The pinning bit doesn't raise an error, it just doesn't work at all;
Nothing is appended to the buffer. Which is odd, because if pinning is
unsuccessful it should still append the entire note as a string.

Any way, been tearing my hair out for days trying to get this to work
and have given up. Wanted to commit this for reference, but I'll revert
it and follow-up with a commit that does work, albeit with a less ideal
test.
Revert "Commit for ref only - Add tests for pinning / unpinning"

This reverts commit bae7514fadc0e721f38d2a8af63980a665fa1aa6.
Add working tests for pinning and unpinning functionality

Also update the note on how to run the tests using the reduced vimrc.

The sleep commands are required for the pinning and unpinning tests to
work reliabily. I don't understand why though. For reference see the
following commit with a preferred approach to the tests that
unfortunately I couldn't get to work:
