fix(data): add codes to remove db index of reading:deviceName:resourceName when deleting readings

[judehung]

When adding readings, a redis sorted set will be created as db index for
the relation of reading:deviceName:resourceName, and this index will be
used to query readings by deviceName and resourceName.

However, the current implementation doesn't remove such index when an
associated event is deleted, thus generating incorrect query result for
readings.

This commit fixes this bug by adding codes to remove db index of
reading:deviceName:resourceName while deleting readings.

closes #3774
