This fixes a problem where the SDK receives an existence filter mismatch and clears the mapping of documents to targets, but does not receive another snapshot that also clears the snapshot version (i.e. the device went in the background and did was not able to actually process a re-run of the query).
The change that this PR makes is that we always reset the lastLimboFreeSnapshot version to 0 if we get a target mismatch.
