Title: Improve handling of GML geometries with references

In sophisticated GML encodings, geometries can contain references to other geometry parts, e.g.:

This patch does the following:

* Parsed geometry properties inside geometries respect the configured GMLReferenceResolver
* Inserts into the SQLFeatureStore do not fail if envelope for a feature can not be calculated due to geometry reference issues. Instead, a NULL envelope is used.
