Retry in CellDatabases fixture when global DB state changes
There is a NOTE in the CellDatabases code about an unlikely but
possible race that can occur between taking the writer lock to set
the last DB context manager and taking the reader lock to call
target_cell(). When the race is detected, a RuntimeError is raised.
We can handle the race by retrying setting the last DB context manager
when the race is detected, as described in the NOTE.
