OmeroCpp: Disable remaining integration search test

[ghost]

This should remove the intermittent integration test failure we're seeing.

https://ci.openmicroscopy.org/view/Failing/job/OMERO-5.1-merge-cpp-cmake/ doesn't run the disabled test anymore, but snipe failed again with a test timeout. In general, this looks OK to merge.

I think the timeouts still need work, but I'm not sure about what we're doing wrong here to fix it.

I agree about the timeout issue being annoying. The Java tests suffer from the same thing. On the Java side I tried using a back-off time value for the command timeout. That value was calculated before each test class was run and should have been an indicator of the "latency" of the node (i.e. higher value would configure the command object to wait longer for the operation to finish on the server). I'd say it works in 50% of the cases and we still get timeouts on the Java front. There is hope that @mtbc's work on graph traversal will speed up some of the command operations (delete, chgrp etc.), so until then I don't have any other ideas.

I certainly hope it'll help, especially in the cases where there are many model objects involved that individually may or may not be orphans (like a dataset full of images). However, we may have to solve separate issues like http://trac.openmicroscopy.org.uk/ome/ticket/11084 before we can get these operations anywhere near as fast as they should be. (I'll also look for opportunity for speedups once #3000 is in.)

Jotted down under https://trello.com/c/Gsc76NVp/312-disabled-tests ; merging.
