In Redis, scores of sorted sets can be floats – so we should use `parseFloat` instead of `parseInt` when converting from string to number.
Should not lead to #4939 again, as `new Date()` works regardless of whether it's being passed a float or integer.
new method emptydb
use emptydb instead of flushdb, flushdb removes indices for mongo which
breaks search tests
initialize meta.config properly in tests
enable nodebb-plugin-dbsearch for tests
