fix(offline): let the cache drop what was deleted elsewhere

Browse Source 
The trip sync and every repo list only ever upserted, so a place a
collaborator deleted while this device was offline came back on the
next offline read, and a trip the user had been removed from stayed on
the device. A sync and a full list now replace the trip's rows, keeping
only the ones created offline that have not synced yet, and a cached
trip the server no longer lists is cleared.
