Fix tst_qquicktextedit

- Use showNormal() instead of show() to keep expected window sizes on
  fullscreen platforms.
- Use consistent point size for hAlignVisual
- Do not query for QQmlComponent::Loading on remoteCursorDelegate: when a new
  connection is established to the test http server, it will setup a single
  shot QTimer with a 500ms timeout that will trigger the reply to be sent
  back, making the call to sendDelayedItem() obsolete and reduntant. Also, it
  means that in some platforms, data will arrive back to the component before
  the check for QQmlComponent::Loading is executed, causing the test to fail
  since at this point the status will already be QQmlComponent::Ready instead.

Fix tst_qquickpath not to use fuzzy compare

On arm platforms, qreal == float. QPointF stores its coordinates internally on
qreal variables (float on arm). When QPointF comparison takes place, a call to
qFuzzyIsNull(float) will ultimately be triggered, causing the test to fail for
some values, because the epsilon of 0.00001f is too small.

In the particular case regarding BB10, the comparison between QPointF(100,
150) and QPointF(99.9999771, 150) is failing because of that.
