LPS-47182 Update solr4-shared to not force commits

Modify [solr-blueprint.xml](https://github.com/arboliveira/liferay-plugins/commit/de2e68c744bdff37930fe7be7b91198c644f73da) same as [solr-spring.xml](https://github.com/brianchandotcom/liferay-plugins/commit/07a8bdddc17932e1f4f2b23cfec1cff4a6f15a53), so the change can also take effect when the plugin is deployed as an OSGi module.
