v7.0.0 breaks EARDBD report plugin loading, due to leftover code from testing

[CharlieThornton33]

In release v7.0.0, no matter what is set in ear.conf EARDBD will load the dummy.so report plugin, and hence is unable to write to a database. This is due to a leftover instance of hardcoding dummy.so, which presumably was used for some sort of testing prior to the release:

EAR/src/database_cache/eardbd.c

Lines 165 to 170 in 4bbb9de

	/* Reporting plugin */
	if (state_fail(report_load(conf_clus->install.dir_plug, "dummy.so"))) {
	// if (state_fail(report_load(conf_clus->install.dir_plug, conf_clus->db_manager.plugins))){
	edb_error("Report error during loading: %s", state_msg);
	exit(EXIT_FAILURE);
	}

Removing line 166 and uncommenting line 167 resolves the issue.
