[ticket/10491] Install board once per test run.

This is how things used to be. Installing for each test class brings
3-4x performance penalty compared to installing once for the entire
test run. However, with a single installation for all tests an
individual test can see different data when it is invoked by itself
vs when it is executed as part of the entire test suite.
