UITK Test install_plugin_qmltypes fails under Qt 5.5

<kalikiana about qtestroot, this is the error that would show up with qmlapicheck and launcher, until we added a hack: qmlRegisterSingletonType<QObject>("Qt.test.qtestroot", 1, 0, "QTestRootObject", testRootObject);
<kalikiana> now since it's showing with qmlplugindump however I suspect we don't want to hack that, too
<kalikiana> I would suspect there must be a private file from qt that would make this work, but I don't really know what to look for.. but it may be better to investigate that than to hack qmlplugindump
<kalikiana> the error is a side effect of importing QtTest to be able to use TestUtil

As a note, I workarounded this by commenting the line ~780 in tests/apicheck/apicheck.cpp, so this is not blocking testing Qt 5.5 unlike bug #1484004

The commenting out does not seem to work anymore:

Nor not commenting out:

I've created https://codereview.qt-project.org/#/c/127822 let's see what upstream says

The patch seems to resolve the issue, although upstream hasn't accepted it yet.

Currently this does not need UITK actions anymore, unless the upstream decides againsts merging the proposal.

This bug was fixed in the package qtdeclarative-opensource-src - 5.5.1-2ubuntu2
