Adjust for WikibaseDatabase 0.2 release
Update Schema.php to use new schema specification
Correct most obvious parts of schema

This is from the following proposal
 - https://www.mediawiki.org/wiki/Extension:Wikibase_QueryEngine/SQL_schema_proposal

Also added some TODOs regarding this scheme
Update wikibase database version
Do not add unused and already covered value_identity field
Uncomment "composer update" in PHPUnit bootstrap
Change the globe/geo handling to latlong handling.
This is what the handler was doing now anyway.
And we do not need to pin down the schema for globe
yet as we will not need it initially anyway.
Improvements to LatLongHandler
Replace DataValueHandler::getWhereConditions with DataValueHandler::getEqualityFieldValue
Use int rather than bigint to prevent sqlite error
Restore PHPUnit flag
Merge pull request #2 from wmde/entropyChange
