test/sr: Free SRVs before replacing them in test_sr_setup_srv()

Stop leaking parts of the shared random state in the shared-random unit tests. The previous fix in 29599 was incomplete.

Fixes bug 29706; bugfix on 0.2.9.1-alpha. --- changes/bug29706_minimal | 4 ++++ src/or/shared_random_state.c | 4 ++-- src/or/shared_random_state.h | 2 ++ src/test/test_shared_random.c | 4 ++++ 4 files changed, 12 insertions(+), 2 deletions(-)
