Ensure we don't try to take exclusive locks if we already identified a shared lock ReadConflict.

And raise a place-specific exception for that. Turns out our implementation of readCurrent() immediately makes a database call and raises ReadConflictError right there if it finds a change. So the test was getting a false positive for awhile.

Fixes #310.
