ISPN-3809 Manual indexing cannot be triggered when running in server mode

The MapReduceInitializer is not loaded from server classpath due to misconfiguration of module.xml and as a consequence the m/r task is not properly initialized.

* Add ManualIndexingTest for server
* Fix module dependencies so MapReduceInitializer gets loaded properly
* Also modify RemoteQueryTest.readClasspathResource to use Util.readStream instead of duplicating the code
ISPN-3184 The DELTA_WRITE flag should force a remote get during state transfer
WIP manual eviction does not update the index, and it should, provided there are no stores configured

* Add a potential fix
* Fixing this for in-DataContainer eviction would be harder, as no EvictCommand enters the interceptor chain
