refactor(database): get rid of the dependency on hstore

Browse source 
The hstore extension was briefly used at some point by miniflux, but not
anymore. Yet it's still required to deploy miniflux, as a hstore column is
created then destroyed during the database creation/migration. This commit
refactor the migrations (scary!) to get rid of hstore, so that it doesn't need
to be installed/present when deploying/running miniflux.

This should close #3759
