Revert "Add getMessage tests with Short and Long Contexts"

Looking at the getMessage function the long and
short contexts should be strings not bools.

I was misslead by the defaults thus these tests
aren't actually testing much and should be removed
to avoid misslead more people!

This reverts commit cd9711ea350e9367829702eddc0adad8c9d88afb.
