QQmlDataTest: fix dataDirectoryUrl generation for paths in qrc

When the data directory is located in qrc (like on Android), the data
directory url was generated incorrectly, missing the last '/'.
As a result QQmlDataTest::dataDirectoryUrl().resolved("something") call
was providing incorrect results.
This patch fixes it, which allows to unblacklist
tst_qqmlqt::resolvedUrl() for Android.
