test(polecat): skip beads-unavailable test when bd is installed (#244)

TestGetReturnsWorkingWithoutBeads assumes bd is not available and
expects state to default to StateWorking. When bd is installed, it
actually queries beads and returns the real state, causing the test
to fail.

Skip the test when bd is detected to avoid environment-dependent
failures.
