upgrade hibernate-core 5.1.2.Final -> 5.2.10.Final (fix travis)

fix schema init in travis.

modify test configuration as default (default_schema == db.user) is not
compatible with previous behavior (we use a schema named the same than
non-test db.user). Basically, cancel default owsicore_test default
configuration with an explicit hibernate.default_schema=owsicore
